I use a hartke lh500 head paired with an avatar b210 neo cab and although I have yet to gig, (working on that) this is an outstanding rig in my opinion. It should be plenty loud enough to handle any coffee shop or small bar.
I don't think you specified any aversion to buying used, but I got my rig right here on the TB classifieds for less than $400

better bang for the buck with used.
Good luck on your search.
