I've found quite a few reasonably priced at www.Amazon.com
And since I'm a new switcher - I've gone through my stash and searched for them at the made4mac link on www.apple.com to see if they're compatible.
If you have a CompUSA nearby they carry Mac games. I have picked up a few there. Most of the CompUSA stores have a Apple section for compuers and software. http://www.compusa.com/locations/default.asp
Look for the "A" next to the store info
