Pat, years ago after doing much research and finding Wayne to be a distributor for these things, we sold quite a few of them, until local 'Rental Places' started renting them. We kinda steered away, but when Sam's Club came onto the scene about 20 years ago and started selling them for like $325. a pop, and we were paying $700 and $800 a pop [w/shipping], we looked into buying from Sam's. After talking and comparing pieces, we were told by Wayne themselves that Sam's Club actually sets a different kind of specs and only Sam's Club is allowed to sell them under this classification. The major differences were .050 aluminum vs .025 aluminum. Ballasts were of barely an outdoor tolerance and the rating was far less than what we could buy direct from Wayne.
It became much easier to just send these people to Sam's Club directly and try to get the rest of their business. In that respect, it worked out better. We would tell the customer, you can buy 3 of theirs after they burn out and get all dented up to one of ours and still save money. They liked the honest approach and generally gave us other business.
