I purchased the Quantum XL6000 machine in March  2008 and love it. I had trouble in the beginning getting it to work with Vista. I ordered a new cable to connect the computer to the machine and no problem since. Sews out beautiful designs and love the endless bobbin. True the manual is not user friendly but with some time and practice I figured it out. Would love to find some videos. The machine is a very strong machine, does not seem like a plastic box as some of the others I tried. October to December the machine was use almost daily, I made gifts for everyone on my Christmas list, no problem....
