Newegg also has the Rosewill RK-9000BR which you might consider. It's ~$110 right now. Another option would be the Leopold FC200RT/AB, available from Elitekeyboards for $109.
According to a few people around here, the Rosewill is very similar to the Filco. Costar stabilizers, etc. The Leopold has Cherry-style stabilizers on the large keys, which some people don't like as much, but they've been working rather smoothly for me. I wouldn't be able to directly compare to any of the boards on your original list, unfortunately, as both of my boards are Leopolds.
I think that whichever route you take, you'll be happy as long as the switches work out for you. If not, there's always the classifieds here.
