Selling my FireStudio in absolutely perfect condition, not a scratch on it, kept in a smoke free studio.
Just recently I got myself the RME Multiface II, and thus have to part with the FireStudio.
In my opinion this is the best bang for your buck, especially giving it's number of I/Os,
robust metal built and strong headphone output. I have the original packaging and stuff.
Would let it go for 130 yoyos, including P&P.

Here's a nice review;
