I recently sold my HQ 16 with ProStitcher via Craig's List. It was in great working order.
I now have an HQ Avante, with a smaller length table, but no computer, from a friend who upgraded to a HQ Fusion with computer that was a floor model.
The whole situation was win-win-win-win situation.
Check out all the machines and find what you bond with. Then check for used machines. There are many quilters who upgrade and want to find a good home for their machines.
