Asbury030,
after searching the i-net, I found the one offered by our hosts to be two things, cheap.. $49.99+shipping (5.00) and it doesn't need a screwdriver to calibrate.. BTW calibration takes 1 min or less...
excellent investment IMO..
HTH,

The one from this site is a quality product, but another good one is RHS-10ATC. That's what I use and I've found it to be very reliable, though it needs occaisional calibration (but comes with the screwdriver!).
not sure where exactly, but i remember a couple of weeks ago reading that a company was having a sale on them 23.00............look around , you can find much better prices.
