I was trying to find a 20GB model back when I bought my PS3 last February. I never managed to find one, so I just ponied up the extra cash on a 60GB unit. The SD card reader is actually quite handy for me, but it's not worth the extra cash. And, I don't use the wifi, I have it plugged into the router. If you're interested in a PS3, I'd totally jump on a 20GB if you can find one. Just swap out the HD for a bigger one and you're set.
