Ok, so I'm buying a drum machine this weekend and these are the two within my price range. I have heard the Alesis is dated, and I have heard the Boss is difficult to program. Can someone give there opinion?
I think Roland has the best drum modules for the Roland v-drums so no matter how hard it is to program, I would want to go with the Boss...

depending on what you will be using it for, I think youll be happy with either one though.
