OK, we appear to have an issue here, so let's debate it.
You appear to have a problem with Simon Willis - that's a specific issue between yourself and him.
'Dealers all deal between themselves'. - they do the world over. Every dealer has a list of customers and coins they require. They are hardly going to say I am not going to buy a coin for you that you want because it comes from another dealer! They usually have a good sense of underpriced coins, and also have to buy to offer a broad range of items when stock is short. i.e they have to buy coins, but other dealers are only a small section of the market place.
'set up price fixing between themselves'. Example? If a coin is common there is no way that the market can possibly be rigged. If it is rare or highly desirable, then the number available is unlikely to exceed one or two in any instance. The only instance I can think where there is some attempt to link coin pricing, is where the coins are slabbed, with a given number equating to a certain price. If people will buy coins unseen based on the slab number, that is a form of price fixing because (leaving aside the ability to resubmit to receive a higher grade), the grade is deemed to be set despite only forming one opinion amongst many. The same can not be said for raw grading whereby it is accepted that opinions differ and so the price for a given grade has more flexibility. If a coin comes from another dealer, then the selling price must inevitably be higher than the purchase price for the new owner to make a profit.
'shuffle customers like cattle'. Not sure where we are going here. I can't think of any dealers who consciously try to move their customers on to the next table. They certainly keep their list of customers to themselves, which is normal for any business. A dealer might tell a good customer where he can get a specific coin, but that is doing someone a favour on the back of past sales.
'lie on eBay'. Don't know as I haven't bought on there for well over a year. I haven't the patience to trawl through the more than 100K British coins listed.
'don't really have as much knowledge as they wish they had, but do they HAVE to be so nasty???' Again, a bit of evidence would help would help if you want to throw stones. We all wish we had more knowledge. Every area has someone who knows more than the next person. Judging by your post on my profile I assume you have included me in this section. For those who haven't looked it reads 'Gosh ain't you a fine example of the nasty arseholes I said populate this forum....negative nelly should be your name......you are certainly no expert in anything except bullshit'. If you would care to elucidate with specifics, I can make a reasoned response. If it was in relation to my reference to the NNC slabs. As 'Centisles' on eBay, he acquired a reputation on both sides of the pond for grading things much higher than anyone else. If it was with regard to the 1911 slabbed by a company neither of us have heard from, then the uplift in price from a PCGS or NGC 65 rating should be enough to cover the cost of slabbing.
I also note you mentioned trolling on the MP thread. I made the not unreasonable assumption that you too were trolling. Your first 8 or 9 posts promised much, but then on Christmas Eve you managed to populate the entire first page (but no more) of the 'Free for All' forum topics in the space of a few minutes with replies, many comprising a few words with little in the way of punctuation or properly formed sentences. They hinted at sensible replies, but said nothing informative as there was no corroborative evidence or reasoned argument for the statement. A post asking for an Ansell sovereign is ok. You then listed 10 or 11 coins in the 'Items for sale'. For someone with less than 50 posts in total, nearly half of which were the mechanical replies made shortly before followed by listing items for sale, you were following a tried and tested method used by people trying to ingratiate themselves with a view to selling coins via something resembling a pyramid scheme. Overpriced silver slabs are the most popular product in this area. I think our friend Henry was the last person to try this on here.
As I also mentioned, Chris is kind enough to provide this forum FOC. Whilst he has included a For Sale section, he is first and foremost a dealer and publisher, so we don't flood his website with adverts for our own wares. Certainly not with what is virtually an introductory message.
Reasoned debate is always welcome here.
