I don't know, I've had the lightbridge for a few years now. It used to be my main interface when I was still relying on PT M-powered (with AD16x's on the front end.) Now, I use it for setting up backup or aux systems, and it's basically reliable as far as I've experienced.
IIRC, it was absolutely miserable getting it working at first - lots of quirks with the driver installation, setup, getting clocking right, etc. But once I got it going, it works well and certainly gives you a ton of digital I/O for the money. When I have to do live electronics stuff (like live processing of audio for new-music gigs), my usual setup is a Rosetta 800 or AD16X feeding the lightbridge to MacBook Pro running, Live, Max, Logic, or whatever is needed. Works fine for me.
