I just finished putting a top and wheels on a kitchen type cabinet for my HQ... As far as I am concerned, I wish everything in my house was on wheels. Must admit that I haven't set up my HQ yet to try it out. I use my Janome 1600P on it and that's my best piecing machine, so I make a number of tops and then finish them all before I take the Janome off the frame. But regarding the wheels, I think what I have now is ever so much more stable (and level) than when I was using the HQ on the folding table from Wal-Mart.
