Hey Matt,

Actually, just yesterday one of the guys in our club who flys IMAC and is building a 40% Carden Extra told me about those regulators. Apparently lots of the IMAC/giant sclae guys are using them and they have a good reputation over there. They do have great specs on paper. I like the ones with the Reliswitch built in - although you have to remeber to unplug them at the end of the day, especially if you are flying Li Ions.
