@testeshome -- good question and don't ever hesitate to ask a question on this forum. That said, I remember when I finally noticed the search bar on this forum. I regret to say I'd been on here a while before it occurred to me I could search the forum for keywords of past discussions. Give it a try and you'll find some good discussions about vacuum pumps. As far as your question about which vacuum pump is best, I really don't know. Personally, while I used one to help with blood flow to the penis early on in my recovery, I never successfully used it to get ready for the sex act. So there's undoubtably people on this forum more knowledgeable than me about vacuum pumps. That said, I just picked a cheap on (about $30 a year ago) off Amazon that had a large number of good reviews. I just wanted to try one without spending too much money. It seemed to work okay for what I wanted, but maybe a more expensive one would have worked better (although I kind of doubt it). But as I said, do some searches and you'll find better advice on this forum than I can give you on vacuum pumps. Best wishes.
