any of you use a keyboard on the PS3? if you do... do you like it and is it worth purchasing?

I have the PS3 Keypad, it works okay, but could be way better for $50. Almost all USB and bluetooth keyboards and mouses work for the '3, Logitech makes a full keyboard for the '3, It's the only officially licensed keyboard out. I may get it cause you can find it cheaper now.
