I used to have one of these while living abroad, and got used to the concept of using a compact electric drumpad set as a MIDI controller for great drum soundbanks such as Addictive Drums or similar plugins.
I should say though, that as a standalone I wouldn't easily use it. I'm not really a fan of how its internal soundbanks sound, neither of the included reverb effect.
But considering the application I wanted to use it for (triggering drum samples from my DAW), it does get the job done, although I wish the pads were a bit more sensitive.
And it really is the cheapest solution in this respect if you're looking for a real drumset feel to your recordings.
Only other contender in this respect is the Yamaha DD65, which has alot more to offer actually (decent internal drum sounds, possibility to connect to external drum modules through MIDI connection, an array of effects, etc.), but for almost twice the price.
