No idea what your budget allows, but I've been very happy with my Pace Peacekeeper booth.  You have an out of the box set up with a solvent safe fan, lighting, filter holder for 1" furnace filters, aux power outlets and a 4" exhaust fitting for exterior venting.   The one I have came with a 265CFM blower, so theoretically changes its air about every 2 seconds.  I'm sure inefficiencies in duct resistance, etc reduce that, but even if it is changing half that often, it's pretty dang good.
