Kathy,
I've used the AMP for several years now. It is a great piece of equipment, but if you are doing several frames at once, it may get your arms a bit tired. It does me, and I do a lot of gardening, exercising, etc.. I do think the 400.00 price tag is a bit excessive for a used one.
We just purchased an electric model by Cutting Edge Designs while in Atlanta. The owner of the company is a retired engineer that helped design most of Fletcher's equipment, including their CMC.
On this one you can sand two legs at a time. The motor seems to run slow enough to not take off too much material at once. They let me try it and it seemed to work great, of course I only used the mouldings they had on hand. I won't be able to set mine up here till next week, but I have high hopes for it.
If you want to talk to Cutting Edge Designs their number is 877-282-4048. The price is 399.00--at the show you got an extra attachment with that price. They are just the nicest people--the owner and his wife were there together. We went back to see them several times before we bought, and each time they were busy, busy. I think they did very well at the show. I hope they did, I like to see the nice guys win once in a while.
Feel free to e-mail me if you have any questions. I am too picky for my own good and I sand everything!!
