Hi,
As a minimum I would start with an S-Video deck with Y/C output.
They might all be discontinued but the more expensive (about $400) JVC consumer decks had built in Noise Reduction and TBC, called Digipure (I think if its called Digipure it has both DNR and TBC). We compared the playback of a JVC HR-S9911 (consumer SVHS deck - about $400) and we preferred the quality to a Panasonic AG7650 (multi thousand dollar professional deck).
If you can't find a JVC S-video deck this might do it (double check and make sure it has TBC):
JVC DH30000

If the playback quality is as good as our JVC HR-S9911 you will be very pleased.
Two units available on Ebay. If the S9911 is in good condition I highly recommend it:
