yeah man one of the guitars with a floyd rose unit is the b.c rich warlock it's a real classic man. and this year they released a 7 string model in that even the neck is adjustable an added advantage and if you are going for a good one make sure it has two or more pickups if it just has 1 then its of no use so if u are into metal you would love the shape of the warlock and also make sure that the tremolo is working perfectly..............................

good luck :D :D
