I have a Beseler 23CIII. I haven't needed customer support (the manual is actually enough for what I've needed). It's sturdy and durable, I'd say. Several 23CII were in use at a museum school darkroom I used and they survived pretty well. They definitely got abused. For personal use, I think you'd have to be very rough to mess it up - regular use isn't going to hurt it. Mine has been moved from one darkroom to another (different state) and it's fine.
