Hello, I've realized that its going to take a while until I can play drums well enough to record with bands (as I am a guitar/bass player that dabbles in drumming) and I've been thinking that maybe it would be wise to invest in a drum machine... i need something that can go pretty fast, and is able to do blast beats and double bass (these two are essential). I'm thinking in the 100-250 dollar range... so anyone who knows anything about drum machines, let me know.
