Country and Jass man
I use an Acoustic Image head for DB. Like this one: http://www.gollihurmusic.com/product...ARUS_PLUS.html
I put a SansAmp BDDI in front for slab: http://www.google.com/products/catal...d=0CCcQ8wIwAg#
Those are pretty compact and under your price limit. $1200 U.S. One heck of a lot of good sound plus tone shaping there with those 2 units.
And I use an EA Wizzy M-line cab: http://www.eaamps.com/index.php?p=wizzym&m=products
Satisfies all my needs. That and my upright, my Lakland Bob Glaub, and my Lakland Joe Osborne 5.
