I stumbled across this old post, and just had to add my two cents worth.
I realize the OP was asking about the worth of this camera for day to day use. And I agree that even if it were free, it wouldn't be worth trying to use it to shoot video in a digital age.
But...
The BVP-3 with the attached BVV-1 record deck is not just some old Betacam. It is THE Betacam. The camera that started it all.
The BVP-3 should be on the list of other gear that changed the TV world, and should have a place of honor, and not be dismissed as old junk.
Until the BVP-3 and the single tube BVP-1 (not really considered a broadcast quality camera) came along in the summer of '82, if you wanted portability in a broadcast format you either shot on 16mm, or had your camera tethered to a separate 3/4, or 1" machine. This camera is as significant as the RCA TK76, and since it was made in much fewer numbers than later Betacam models, anytime you can get one it might be worth having as a collectable.
