I would recommend NOT getting an Alesis. The company is bankrupt and it would be in your best interest to not get on a wagon with a broken axle.

Try out the instruments because the "sound" you are looking for is based on your ears, not anyone elses.

Consider getting a controller like a Fatar and sound modules like Emu Proteus et. al.

Friend of mine bought an Alesis and he likes it just fine, but he's disappointed in some of the sounds and how it is limited. I bought an Oberheim MC3000 controller (when it was available cheap in the U.S.) a sampler and have been very happy that at any point, I can add on very easily.
