Donny,
A couple of suggestions would be.
1)Peavey KBA/30. A small lightweight 40 watt bi-amps keyboard amp with a balanced mic input. Very small, lightweight, and a very clean sound. Price is retail $349.00. Quite amazing for it's size! The only biamped model of it's type. Three channels.
2) Roland KC100 and KC300 are also very good but not quite as small or reasonably priced!
3) I would also recommend the prime PM 50. Although it is made in Korea, it has two mic inputs, reverb, CD inputs, 2 keyboard inputs, external speaker jack, 50 watts, 10" speaker and a horn, and a speaker stand hole in the bottom with a price of $249.00. the size is a small cube.
