Imho, I wouldn’t pay much either, A. Certainly nice to have them if the chance is there, although you’d have the hassle and risk of trusting someone/s to do the ‘transferring’ for you… Would they then return them to you safely… Or at all.
If Frank Quinto’s still working in the Archives and they actually do release something (zzz!), then most likely the shows will be the rarest of the rare anyway.
As for the VHS tapes, then I’d definitely grab those, could be many Amateur and un-circulated gems hiding away… Still the same problems as with the tapes, though ^.
