I ended up with this rig in a deal with my local pawn shop manager. I have NO expertise (please double check part numbers against photos) and I don't have the pro grade video recorder that this receiver attaches to, so I cannot test, but the transmitter powers up and the microphone appears functional. I did step up and pay a fair amount for the system, but I did so because I trust the guy, the kit seems complete and it is super clean. Looks like this rig is modern (currently still offered by manufacturer) and sells NEW (Nothing used on ebay) for about $1299.Whats it worth?  Make me an offer...
