Thanks for the input.
I picked this up late Friday and didn't have much time to research it.
Craigslist (Kijji) has 3 others from $500 to $900 on it from the same manufacture.
The manufactures web page has two dealers listed but their phone numbers interconnect and the only person who could talk to me about the lifts is away till Tuesday (long weekend up here).
Will contact the MS Society on Tuesday and see if they are interested. Thanks pwd72s for the idea. If they aren't, then the MD Society. If not maybe I'll drive to Phoenix with it per Don's recommendation.
