Todd also has the Airpower proportional valve available at a very good price:

I'm waiting for a report on how well it works from Todd...
If he says its OK, it should be a good alternative although the UP6 works very well in my opinion.

A friend got an Airpower valve. It is not proportional, just on/off. It is just a simple spindel valve like a robart retract valve. Saw the inside of it.
