The PU mentioned above is good but they were bought out recently and support is not what it used to be. It's probably still the best performer though.
Progressive Industries, not "PU". ;) As to whether a PI model is the "best performer" vs a comparable model from TRC
Technology Research is as much internet folklore than anything else. Both are reliable products, each offers advantages the other may not, one example being a trip delay for the TRC EMS, no delay for the PI version. Some prefer the higher cutoff threshold voltage of 104 vac for the PI, others are quite happy with the TRC's 102 vac. Examine the specs for each and determine for
yourself which is "best". ;)
