I swear by my Bose L1 Compact -best $900 you can spend. I also have a Roland BA-330 that plays in stereo and is very good sounding in a non-Bose way (more of a classic amp sound). I have heard and would also recommend the HK Nano 300. Over in the General Arranger forum there are a few posts about the smaller Bose units, mostly good reviews for very small venues.
If anyone is interested, my BA-330 is FOR SALE. PM me.
