You seem to be throwing the word "long tail" into the answer, but I still don't understand what makes Chec different/better than Gumroad for selling "long tail" items. I can sell both my app and my PSDs through both Gumroad and Chec. I really don't see a difference other than the fact that you can set fixed shipping prices. Maybe Gumroad doesn't support Paypal?
Can you compare and contrast the two in a meaningful way?
What can I do with Chec that I can't do with Gumroad? And for that matter, what does Gumroad do that Chec doesn't (yet) do?
