There's also one on ebay right now. Don't get false information though. A debugger DOES NOT have more RAM than a regular PlayStation. A Debugger is basically the same as a retail unit except for the color, it has no region code check, and you can hook up a serial cable to the PC to do printfs to aid in debugging.

For most people a debugger is not much better than a modded system. A Modded system is a lot cheaper too.
