Just a heads up. Found these on Ebay.

Pair 6 FT ADAT Cables

$6.53/pair with free UPS shipping. They're built just like the high dollar Apogee cables, really thick with gold ferrules, little captive silicone end covers. Although I don't seriously think they're as good, in the 3 ft and 6 ft lengths he's selling they seem to be fine for a permanent installation. I have received 4 or 'em and no problems so far, just ordered 6 more.

I bought some just like this (12') off ebay several years ago (maybe from the same seller, I don't know), and they're still working fine. I use them from the Giga Studio PC's, and a second Mac (VI player) to a MOTU 2408.
The outer jacket makes them nice and flexible, and (seemingly?) much less fragile.

The only warning I'll give on ADAT cables is about the Monster brand.

I bought a lot of them for about $3.00 a piece. They work fine but have these big connectors so if you have ADAT IN/OUT next to each other they're kind of worthless.
