I bought one of those bridges, mostly for the hell of it, figuring it would be a total piece of crap. Surprisingly, it doesn't appear to be too bad. My complaint is with the headpiece; next to none of my strings fit correctly in the grooves because of the core wire doubling back after going around the ball end underneath the wrapping, but a little filing could fix that. What it doesn't show you is that you need to route out a space for the bridge to sit properly on a body; but the knobs extend outward if you pull on them, which makes for easier tuning of individual strings. I haven't used my bridge yet so I can't comment on how well it stands up to use.
