I have to thank vacuum dynamics for the Alcatel idea. He’s always saying how good they are. Found some deceit ones on eBay for $280 each shipped and not really thinking offered the guy $750 for 3 and he accepted. All 3 run perfect but one has a crack plastic shrod, and now I’m reminded of all the stupid money I spent on across international vacuum pumps.
I’m sure there are other really good cheap vacuum pumps that were ignoring out there.
