I'm in the process of doing an acoustic to electric conversion on a well used Stagg fusion drum kit at the minute for my home-based silent rehearsal project. So far I'm just over 200 quid (used TD6V module off the bay, DIY drum triggers, second hand Stagg kit and Alesis cymbals off gumtree), but it takes some DIY and experimentation, and I'll probably break the 300 quid mark by the time I'm finished (need pretty much all hardware replaced since the stagg stuff is AWFUL). Just putting it out there as a possible option.
My thinking was it would feel more like a real drum kit. The drummer in my previous band bought a TD3 and gigged it for a while (which was great - nice quiet stage!) but lost interest in it as the feel wasn't right.
