I use an old Peavey 4x10 at a rehearsal room locally. It weighs a ton, but does "warm vintage" very well. You can pick them up cheaply. However, I wouldn't like to have to schlep one around. If you want light, new and vintage sounding, the Aguilar 4x10 is nice (I tried one when I bought my AG700), but around double your budget.
I have one of the older Epifani 3x10s, which can do vintage if you turn off the tweeter. That or one of their 4x10s, if you can find one secondhand, would be a good choice, imho.
