I'm looking for a good way to use my A16 with my MacBook/Ableton setup. There are a couple of cool Firewire interfaces (like the Focusrite Saffire Pro 26i/o http://www.sweetwater.com/store/detail/SaffirePro26/) that have 16 channels of ADAT i/o (or 8 using S-MUX). This one in particular seems like a good options because I could plug hardware synths, drum machines, etc. into the A16 then use the ADAT out of the A16 into the ADAT inputs of the Focusrite then on to the Mac via Firewire. This also gives me 8 nice mic pre's. BUT, that's $700.
Does anyone know of an el-cheapo firewire interface that supports 16 channels of ADAT that could basically just act as middleware for the A16 to get signal into the MacBook?
p.s. don't worry, I'm not abandoning Scope

Cheers,
Brent
