I know it's not an option for everyone, but I found that I enjoyed playing the old games on PSVita over the PS3. Of course, I caught them during a sale, so not everyone wants to buy each Final Fantasy game for $5-$10. Having both my old PS1, and PS2, I can just pop them in and use the old memory cards, but they aren't that reliable after so many years.
Might just look for a solid emulator and a good usb controller.
