Theres a lot of stuff out there bro. Triton is tha best as for as keyboards, period. But they cost 2 damn much. I know u can get a Yamaha PSR-225 for like $150 at Wal-Mart, K-Mart, stores like that. Then buy tha MIDI InPUt/OutPUt cord to put it on your computer.
Put it in perspective, visit this site:
www.musiciansfriend.com
They have EVERYTHING u need. U can jsut subscribe for a free catalog. If u can't purchase over tha internet, u can always go to a music store in your are, Guitar Center, or something and pick tha equipment up.
I hope I've been some help. There a lot of stuff out there, just don't spend a lot of $ on it. MusiciansFriend is great. U should find out a lot of stuff there.
