I wanted to add something about post on the internet.
I've been on the 'net since 1989 in one form or another, so I like to think that I have a bit of a clue.
When people like Andrew or Jeff post and publically identify themselves or when they publish a book or a website or speak in public etc, they allow for peer review. This is the same as one would find in the scientific community or, even, in the arts community (yes, even photographers :-)
That simple act - making yourself subject to peer review - adds credibility. Not everyone will make themselves completely publically known. I haven't, for example, and there are reasons for it. I expect people to place less credibility on my comments as a result. That's my choice. I won't get upset by it :-) At any rate, there are people here far more knowledgable than I, which is why I come here to read and learn and (after a couple of years of lurking) participate.
But then I wouldn't dream of telling someone they're wrong just because I said so, without providing substantial proof or detailed argument. That's what you did, Dean. You expected us to take your word for it when we don't know what it's worth. Maybe you're right and maybe everyone else is wrong, but you've neither presented a strong argument, presented proof, or given us reason to accept your word on the subject. All of that is fine, but don't get upset when this is pointed out to you.
I hope your business flourishes and your customers are delighted with the results. I hope, also, that you may be gracious enough to consider that perhaps folks have a point and look into what they're saying and if you don't understand it ask them to clarify.
As for your comments about Epson papers. Well, take a look at EFP and tell me it's garbage (it's most definitely anything of the sort). And bear in mind that Epson doesn't own a paper manufacturing plant and that some of the other papers that you are using probably come from the same factories. Some of us can tell just by looking at the "made in ..." label who makes them in some cases. Sure, they may be different, but they're hardly rubbish, even if you don't like them.
Perhaps if you understood and applied color management practices you'd obtain results that would change your mind :-)
