So funny this thread came up as I am sitting with lower back pain right now. From all of the above I think I may investigate the duffle bag suggestion. I'm finding I love my portable machine carrying case with wheels, BUT it's the transfer from the car that's my killer. The other thing, at retreats I can not discipline myself to get up from my chair and walk around. Also, the tables make my machine higher than is really comfortable. So, that's my story and I'm sticking to it!!! Actually, it's hard to get older and not be able to do things that used to be so easy for me.
