I have an Air Sled provided to me almost 10 years ago after going through vocational re-training. I was a Sears appliance repair technician for about 5 years and never used the kit. When I sold appliances at Sears, I used the air sled from time to time to rearrange the sales floor and it worked great. It's still in great condition and will part with it for a fraction of the cost of a new kit. Send me an e-mail if you're interested.
