Damn... I came into this thread expecting to be able to use that AOL translator thing....
Anyways, it's really up to you in the end. Sometimes $400 is a good budget for a used gun. I got mine for $450, not the greatest by any means but not "crap" either.
Used guns will sometimes be upgraded so you should put that into consideration as well. It's like buying a Civic DX vs a Civic Si or Type R. I don't know if that's a good analogy but still, either get an 'OK' car for $13,000 or w/e or a better one that's been upgraded for $21,000. You still might find that you want to upgrade it a bit later but with the Type R there's already some upgraded parts.
You could buy a new stock Civic DX or a used Civic DX with some mods and maybe a new engine (lets say a K20 vs the stock Civic DX engine).
In the end, again it's up to you but I know that I lean towards buying from the classifieds because it's more in my price range and I like package deals.
EDIT: Also if you're going to that op, I believe there will be rentals available so you don't need to jump in and buy a "cansoft" gun and after getting AV'ed find that you want to get rid of it and buy one from the classifieds.
