Mine were incredibly inexpensive ($85 for the pair, new), and have held up very well. Thumbs up from me. Also, not that it really matters, but I think they're the best looking option in their price range... the flanges are kind of mid-high and the dull silver looks good and wears well.
While Harris Cyclery might prefer the Formula, Trackstar like the Miche:

Now after years of messingering and bike shopping I could agree with that statment. They are tuff, good lookin, use the very common 6001 sealed bearing, and are like everything that Miche makes, a good bang for your buck. BANG!
Either way, I don't think I've ever heard anything bad about the newer sealed versions from anyone.
