The Maranzt PMD-661 (not the 660, though), PMD-670, and PMD-671 all have coax S/PDIF inputs (the 670 is limited to 16 bit, though).
The Tascam HD-P2 also has coax S/PDIF, as does the M-Audio Microtrack II.
I know you said you only wanted two channel decks, but the Edirol R-44 also has coax S/PDIF input, and is in the same price range as the PMD-671 and the HD-P2.
Then there's the Sony PCM-D50, but that S/PDIF input is via optical (could be easy or not, depending on whether or not your V3 has the optical mod).
off the top of my head, that's all I can think of. perhaps there are one or two more that have slipped my mind.
