Electronic drums have come a long way in the past 10 or so years! Technology has bought the playing experience more into line with a traditional acoustic kit, while maintaining all the benefits and versatility that made electronic kits so appealing in the first place. Now days choices range from a kit with full rubber pads all the way to fully hybrid kits (see Roland's Acoustic Design range) that blend the much loved presence of acoustic drums with the perks of digital.
Many electronic kits feature low noise, mesh drum heads that give very natural rebound and natural trigger response, meaning you can use all the typical acoustic drumming techniques. Compared to acoustic drums, mesh heads last many times longer and you can even adjust the rebound feel of the drum without affecting the sound you hear.
A lot of electronic drum kits also allow expansion for adding more cymbals and toms too and because the surfaces are rubber, broken sticks are a thing of the past. No breakages mean almost no ongoing costs. Depending on the kit you choose, double kick pedals and conventional hi-hat stands to be used so you can create the ultimate drum kit to match your drum hero.
As mentioned earlier, electronic kits facilitate the use of headphones, expanding your practice window significantly during the day and especially at night! They also allow your practice sessions to be as private as you want them to be, meaning you won't have to be so self conscious when you don't nail that Keith Moon style fill on the first attempt.
