Have you checked the local shops and prospecting clubs for used equipment? There are clubs in Victorville, 29 Palms, a few in Las Vegas, and likely more I either do not know about of have forgotten. Craigslist may also be helpful. I have one in my shop in Oregon just gathering dust since a stroke, but you are too far away to make that a cost effective option. If, however, the new meds help some of my persistant post-stroke issues, I may want to load it up and join you for a few weeks of shoveling sand and gravel.
