Hey John,

Long time no talk.

About 3 years ago I purchased a Behringer Ultratone K450 FX - a 45 Watt PA / Keyboard Amp and love it.
It has 3 line inputs- I use one for my MP3 player and one for my mic. I quit the piano playing but do play a melodica over the mike.

I play in smaller to medium-sized restaurants and other venues as well as outdoors; it's plenty loud. Also very portable. The RealTracks sound great.

The unit costs about $180 nowadays so it's not all that cheap anymore. I paid around $120.
