Also depends on if you ever see yourself breaking the 10 track barrier that the Ultralite has. Since the Tascam has ADAT so it can be expanded, but you may be able to daisy chain UltraLite's...don't know.
I owned the Tascam for a while, and as far as sound was concerned, it worked great. I think the Firepod pres are a little nicer, but the Tascams were definitely useable. The problem I had with the card was stability. It wasn't often, but at seemingly random times it would have a big sync issue and not record about 1-2 sec. of stuff that was going on. I would then have to start over on that take. Not too big of a deal if its just you, but when you got clients sitting there...That was the only issue I had with it, like I said, it didn't happen alot but enough to make me get rid of it. Hope any of this helps.
