Was wondering how good the Quantum II's are? Gave 50.00 for it from a friend that needed the money, its like new he says he used it twice then put it away.
ill give you a 100 for it. ive had 2 of the Quantum xts., very simular with a few extra features, and believe whites is still doing a upgrade for around 100 dollars to the QXT pro chip, not that its needed. you got a great deal, not a real popular machine and cannot tell you why, i really enjoyed mine and have been keeping an eye out for great preformer.
I too recently picked up a QXT pro. It is different for sure, but the people who have them figured out seem to love them. I'm still in the crawling stage(gotta crawl before you walk before you run!!). In time i'll get it down, so far it seems a bit jittery and I haven't got it dialed in right. Good luck, let us know how you do
