Anyway, the "heavy duty" floyd rose sold by Guitarfetish is made by Ping, and this is actually a really decent trem. You know those nice expensive $1200++ Wolfgang EVH guitars? They use this *exact* trem. The $999 Fernandes Revolver Elite? Yep, them too.
This is an excellent upgrade unless you're already running Gotoh or a good Edge incarnation. The arm collar is slightly unpractical since you basically need a tool to tighten the arm, but I dare say this floyd feels *way* better than OFR/Schaller. It also has a fairly low profile.
Tuning stability is excellent, equal to or better than the "original" floyds produced these days. The knife edges aren't razor sharp, but neither are Gotoh's in case you haven't looked
These items usually sell for $30-50 used on ****, the peavey branded ones I've even seen go for $120 used (though with the lame d-tuna knob attached).
Oh, and you can also retrofit the not-so-nice schaller-produced collar + arm if you absolutely feel like downgrading -- it fits nice and tight in the standard 9mm hole in the base plate.
