Actually, the CM-30 is a good choice. It's great as a practice amp and really good as a near field powered monitor, when needed. I also just got a Roland Mobile Cube amp. $159.00. It's battery powered, with 15 hours of battery life. It has stereo 1/4", mono 1/4", effects, a mike in, etc. Good for my small 25-50 person corporate lunches, with a nylon string. Just used it last night for a monitor. Worked great.
Only 5 watts, though. the CM-30 is an underrated 30 watts.


Both good choices, though.
