I have an old Roland keyboard called a G600. However, the only thing I use it for these days is the piano sound which in my opinion is the best attempt at piano replication I've heard.

Anyway, since this thing's taking up so much space in my bedroom, I was wondering if any of you guys know of a sound module I can buy which would be cheap and would give me the same kind of piano sound that I've been using on my Roland keyboard.

I'm not into mega fancy features or anything like that... all I want is something that will give me a good basic piano sound.

Thanks
