I've been looking around, reading reviews and so far I haven't been able to find any switch pedal where most of the reviews don't complain about a) sound degradation, b) too much hum, c) build quality or d) all of the above.

There must be a decent one out there? They're such an intergal piece of kit to people with large pedal rigs. What do you guys use?

So far I've looked at a Morley, an Art Coolswitch and the Boss AB-2.
