Electronic drumkits have improved over the last couple of years; the quality of build and sound have vastly improved to such an extent that electronic kits are rapidly becoming a lot more popular.
Major manufacturers such as Roland and Yamaha have complete kits for less than £500 and they give the added advantage that you have a multiple choice of the kit you play as it's all programmed into the drum brain.
Electronic kits are ideal for the beginner as you get the feel of playing a real acoustic kit without all the grief about the noise levels. You just plug in your headphones and enjoy!
