I've used a lot of Mustad (a sponsor on FAOL!) and Umpqua hooks, mainly because my local store stocks them. The quality is very consistent and reliable.
I have also been using/buying quite a few Allen hooks....and they are very good quality for a very reasonable price. I just recently got an order of barbless hooks from them, and these seem very nice and there is a good selection of them. They have not just trout hooks... I've also bought steel saltwater hooks and bass popper hooks from Allen Co. http://www.allenflyfishing.com/fly-hooks-etc/
I was also quite pleased with their prices on tungsten beads.
