Question on buying a new PS3

Hey everyone, I'm thinking about buying a new ps3, the old 80gb or 60gb version because I want to have the backwards compatibiliity and also the superaudio cd player. Right now I currently own a 40gb version ps3. I was just wondering if I will be able to back up things that I've bought in the playstation store on an external harddrive then would I be able to load it onto the new ps3? I know that I could do that with my save files, but I don't want to be losing any money when I find out I can't restore my street fighter turbo hd on the new ps3 =/ I already spent around $30-40 buying addons and games.

thanks in advance!

wouldn't that also be a big flaw? i mean I can go to my friends house on his ps3, sign on my psn, and download the things I've purchased. But thanks for the reply though! hope it will workMatrixMario
