I bought a 6000 di Pro SL a while back, and didn't even remember making a post here about it "falsing" when I first turned it on, and I came on here asking about the issue. Well, I had it on the wrong setting for one thing, but it has worked perfectly ever since, and I even made some posts here about how I really liked the machine. But I decided to sell it recently, as I have so many machines. I was contacted by a "buyer", who asked alot of questions about the machine, and I repeatedly told him how well it looked AND works, and had forgotten about the MINOR and one-time falsing thing, which was before I ever took it out in the field. That wasn't even an issue, as it has been perfectly stable and with no falsing issues since. It works great. He bought the machine(not off any forums), but another selling site. He came on this forum and read all my posts, and called me the other night "obsessing" over this machine's condition, and it's STILL IN THE MAIL!! He is complaining about it, and it hasn't even gotten there yet! It's one of the most STABLE machines I've ever owned, with no "ISSUES", and it's in very nice cosmetic shape, too. I'm a fairly easy-going guy, and it takes alot to get me "riled-up", but I finally told him that when the postman shows up with the box, to refuse it and "return to sender", and I will give him a FULL refund, but if he opens the box, it's HIS! I've never seen anybody complain about something before they even GOT it..... I informed him that I could tell that he was going to "knit-pick" it to death, even if it's totally perfect. We'll see....
