i play out 5 times a week with my POD X3 Live.
I would mos def reccomend finding a solid-state(transitor) amp with an effects loop.
that way you could by pass the preamp of the amplifier and use the POD for the basis of your sound.
Either that or an Active(powered) PA monitor. Beringer makes a good one for around your price range.
those are generally 120w and will sound amazing with your POD infront of it.
If you are going for a tube amp, I would say a Vox Valvetronix would be pretty good. but it is a good idea to play an amp before you buy it. Go to Guitar Center and ask a sales rep to show you all the amps in your price range.
check Ebay. I scored a 212 fender for $180 in MINT condition.
Only bid on an amp that is in REALLY good condition. That it will almost always be newer and better taken care of.
