Well, I certainly would not pay anywhere near $1k for a Sound Tech, but for $250 or less they are a great deal. They are always in demand and you could use it for 5 years and then sell for more than you paid.
The nice thing about the ST is that it generates a modulated RF MPX signal, so you can just connect the generator to the ant terminals and be done with it. Its basically a high quality calibrated FM stereo transmitter. It also has a dual sweep function which makes it easy to align the IF for maximum linearity.
From what I understand the SG165 does not modulate the MPX signal on the FM RF carrier, so you have to insert the MPX signal directly into the receivers decoder circuitry. Its FM RF output is very low level and useful only for peaking the front end.
