I'm just making sure I understand correctly -
Decent hardware to capture RCA/Composite outputs from e.g. a VHS VCR will cost something like $200? For Canopus / Grass Valley DV Bridges. There's nothing cheaper.
This is what folks have suggested in a couple of threads I've been in.
FWIW I'm not against buying used stuff, but I can't buy anything complicated. I can barely get new, "easy" stuff to work (like PE).
