I got the Strike Zone kit which is £500 cheaper than the Pro, has only one 12" tom and 2 less cymbals.
Reason for buying it was I'm getting on a bit and was fed up of lugging my big old acoustic kit around, I wanted something smaller and lighter.
So far I've only played the kit twice but I love the drums themselves, it feels like a real kit, unlike the earlier Alesis kit I bought which was all pads. (I sold that to a student at Glasgow uni who couldnt play real drums in digs...)
I admit though I don't like the rubber cymbals and hate the hi-hat...
I bought a set of Zildjian Gen 16 BBs and I am looking forward to setting them up... expensive but I tried them out in the store and they sounded great through the headphones.
There is not a lot of choice though its Zildjian or none... you pays your money and takes yor pick.
You can buy the module and sensors and fit them to L80s or even "real" cymbals (there's a Db limiter on the sensor to cut back the level from a real cymbal), how you fit the sensor though I dont know, do you have to drill a hole in the bell???
Anyway getting off piste a bit I love the kit hate the rubber cymbals.
