Do you know what the different numbers at the end of the
model mean? Is it just an manufacturer code?
The HR20's are made by several different companies, the -100 or-700 number denotes that it is either Panasonic or RCA or whatever, the guts are the same however a couple of them have slightly different dimensions and cosmetics to the LEDS than the rest.
Just get this and be done with it:
