I've never used or heard an Equitech product but certainly have a very well regarded reputation. I had considered buying one of their units at one time. I subsequently bought the BPT due to multiple rave reviews, comments from multiple happy owners and a nice discount on a new unit from the company. After 8 year's of ownership I remain utterly pleased with it. I wish they could have stayed in business as their AC balanced transformers/conditioners are excellent.
