I really like the ZR trem -- it appears intuitive to use, you don't need a tool to adjust spring tension, and I'm told (by my guitar teacher) that tuning is stable.

I don't own one, but I'm drooling for a guitar with a ZR trem for an upgrade in the next six months ...

the price tag is pretty appealling aswell!

also...see for the fret markers, are there any on the top of the neck?
because i could see myself struggling to ajust to the guitar if there are NONE apart from the claw mark at the 12th fret!
