BB,
I'll respond to your other queries a little later. But, if you haven't aready gotten the RF25, I would not recommend it. I got one. I used it three times and the floating part died. About 10 weeks later I finally got a replacement after multiple phone calls. The replacement lasted for about 30 minutes before it died. I gave up on trying to get it replaced, and just wrote the whole thing off as mistake. Maybe others have had a better experience with it.
When it worked, it did what I wanted. But . . . Google the thing. Maybe they've gotten better. When I was having problems with mine, I found through web searches that a lot of other people were having similar problems.
