Re: Thinking about getting an E-kit and know nothing about them
Welcome to the forum!
Lots of good information here about e-drums, modules, mixing / matching, growth paths, etc. Perhaps do some searching on those keywords and see what pops up. Also you may want to wander over to Vdrums.com. There is more, e-drum specific discussion over there than here at DW.
I cannot help you much with Alesis but know my way around Roland products pretty well. Let me know if I can help you with questions on those.
