I have been using a Numark Control (total control/stealth control) with an external soundcard for the last 3 years and have really enjoyed it. The play/cue buttons are the membrane type and are wearing out though. The jogs are too small to scratch with but it has a great selection of knobs and is a great size.
The Reloop Mixage series has caught my eye, but I may try to repair my current unit since my gigs are only paying about $100/week now
