^^ Problem is, the cheapest one is at a markup.
I'd try for a 60gb model for sure -- for one thing, your ps2 games get upscaled as well via the system itself.
But really, if it isn't worth the premium to you, then get an 80GB model off of amazon. Free shipping and no tax, plus any bluray offers that are out there you can take advantage of (be warned, the mail-in free bluray offer takes a long time to process, and the movies are semi-pre-chosen)
Best Buy was having a sale recently where they were including a lot of free bluray movies with the sale of a player (I know Al got like 8 free discs or something, he actually was able to take free blurays directly home from best buy with the purchase), but I don't know if that's only for standalone players. Of course, you're paying tax.... but it might be worth it IF they're doing that "free bluray" offer with purchase.
The other caveat with the Ps3 are of course the games themselves -- I mostly use mine for ps2 games (cuz I never had a ps2). I have played some Ps3 games, which are GORGEOUS but I have yet to actually purchase one. Hopefully this year will bring more fun stuff to the table (like an actual long RPG, please!)
