The upcoming kirtan has motivated some musical consumerism; I traded in an electric bass (and some $$$) for a new keyboard amplifier that will be just the ticket for replacing my homebuilt mixer.
Plusses: Four inputs (one a mic input), and extra aux input for a CD / MP3 player, an effects send (mostly reverb / delays), and line out feeds. Small enough (20" x 17" x 12" / 44 lbs) for me to heft to gigs. 180 Watts - way more than I'll need. A lot easier to set up, and I can use it as a monitor so I can hear myself.
So far so good - I've been practicing with it, and it helps a lot.
