I just googled it, and found loads of Scibor sources, but you already mentioned that you weren't a big fan of them.
You're in the US, if you do opt for Scibor, I suggest
thewarstore.com. They may carry a few
FW bits as well, but I'm not positive, and you'll need to check (if they do, they'll be way cheaper than
FW itself).
Sorry I couldn't help more, but at least I may have saved you some cash.
