Thanks!

I wonder if I can find a local retailer (Seattle area) so I can figure out which tension is appropriate. I'm guessing I need the lightest to start with, being female and having some long-term postsurgical impairment in one hand. Any opinion?
Yes - I'd go along with getting the lightest tension, especially if you've had previous problems. Be cautious to start with. If you get any strain symptoms, the most common of which with these devices is the muscle that runs up the side of the little finger seizing up, then you're overdoing it.
I think the yellow Gripmaster is the lightest (from memory). Hand muscles do build up quite quickly, and I have found that the springs soften considerably with age, so with regular use you may find that you need a replacement, or to move up a grade. But above all take it gently - it's the sort of implement you can do an awful lot of damage with if you're not careful.
