Overcaster
Inspired
And those who like and prefer them, what are they supposed to do? I have a guitar with a Floyd type trem, non-blocked, and it's one of my favorites. I've passed on many guitars because they didn't have a trem.
Better alternatives? Some swear on Kahlers, some on the ibanez patented ones. There are many better ones out there, but the bog standard FR is always on everything.
