Mic Pre Amp, any suggestions? Options

I'm in the market for an affordable mic preamp. I would say between $200-$300. I use and M-Box to record, but the preamps are way to weak.

Anyone have some suggestions?

Thanks

I guess I should add that I am recording vocals and acoustic guitar with a condenser mic (B-1). I'm looking for something that will work in a rack and adds some warmth. I prefer tubes, but that may be way to expensive.

Beringher has a couple of pre's in the $100-200 range, but I don't know anyone that uses them. I've heard they are clean and cheap, but that's not enough to convince me to buy.
