Well, electronic drums are quite more expensive than their analog counterparts... Roland's entry-level
V-Club set (which was what I started out with) retails for just under $1,000 if you shop around. I've upgraded everything on that set including the drum module, so all told I'm up to just over 3 large. The thing is I live in an apartment so "real" drums weren't an option. My drums are quiet enough to play at any time of the day or not and not disturb the neighbors. Plus at any time I can have have 50 different drum kits chosen from an almost infinite variety of drums sounds... Can't do that on the "real thing."
Having said all that, I have a feeling that when I buy a house, I will strongly consider buying a half-decent analog drum set.
