I have an FA-300 TBC that has DUB in, Dropout Compensation (DOC - if any lines come through missing data, it will substitute data from the prior line so that there's only a little distortion as opposed to static on that line) and Adv. Sync (tells the player to slightly speed up or slow down so that the frame rate matches exactly what the TBC tells it). Only downside is that there's something up with the power supply where you have to switch it on and off until it eventually starts up which can take 10 or so tries. Once it's on, it stays running and everything seems to work well on it, though I don't personally have any machines with advance sync or DUB, but I assume that also works. I'd sell that for $300 shipped to the USA which is quite a bit less than the others currently listed ones on ebay. PM me if interested.
Issues is, I don't see at least in your
Amazon link that you actually have "DUB output" on that machine. The other thing that is hard to track down are the actual DUB cables which have a 7 pin connector (one male and one female), but maybe your TV station gave you some of those as well if they had them.
Even if you don't have DUB out, the ADV Sync and DOC features is probably worth having on whatever TBC you end up using as both of those also work with Composite-only transfers and they just require one BNC to BNC cable each.
