I went with the Old Air Products Hurricane unit and painted the under-dash part to match my dashboard. Very nice and whoever designed it added a second thermostatic adjustment for the inside coil (the evaporator) so you can adjust until the temp is very cold but stop before you risk causing freeze-up. Helps balance your control panel adjustment. One of the better designed units I've seen.
