avid, you're right, the Nady looks identical to the old RS model. Who knows, maybe Nady supplied the old model to RS.
The question maybe you should ask RS, is whether this new analog is better in any way than the old one. They are both seven range units for instance, but perhaps the new one doesn't have to be corrected like the old one? Maybe you could find out and let us know.
Otherwise, it seems to have all the features of the old one. (And for a mere $39.95 and a 90 day warranty, you can't go wrong.) The tripod mount is very handy to keep your body away from the unit during tests. You can simply turn the unit on its side on the tripod head, and it's easy to read the meter from 3 or 4 feet away.
