I concur, I am a stickler for quality too. My wife has an Alesis TransActive Mobile. She uses it for the occassional 10-15 people presentation/training. It is ok, but not perfect. You can sit your iphone/ipod touch in it and it get’s charged as well.
We also use it when we have a BBQ out front with the neighbours.
It suits the purpose (somewhat), but is nothing I’d want to advertise, let alone recommend.
The Roland is a different story. However, the only way to convine you is for you to find one next time you are in your gear shop and have a listen ;-).
Be prepared to be surprised, I know I was when I heard it the first time.
