Until recently,
AFAIK, there were no fixed-fixed options for track hubs of comparable quality in that price range. The Nashbar fixed-fixed have even more mixed reviews than the Miche, and are no longer available. I think IRO is offering a fixed-fixed now, which might make it a good mid-priced option. However, when I went with the Miche, the fixed-fixed options were things like NJS Suzues, Dura Aces, Phils, etc. Those hubs aren't really comparable to the Miche in either quality or price.
