I had a Nashbar house brand fork that was decent. Got it on sale for $100. Was going to use it for a project,but didn't get around to it and wound up selling it. It also had canti posts,so you'd have empty posts sticking out if that's a big deal. Several other forum users have used them and given them decent reviews.
