I have two floyd rose equipped guitars ........and i do not need two of them .......So i decided to convert my fender floyd rose special to a normal vintage tremolo, non locking one. I don't care about devaluing the instrument e.t.c So i am going to go with a normal US vintage bridge( by vintage i mean the one with the 6 screws that fit directly into the body of the guitar) and a regular nut....I searched over the internet and found various types of bridges/tremolos......from extremely cheap to quite expensive......can you inform me on what should i look out on a vintage type tremolo???(steel block? e.t.c)

I have found the fender US vintage tremolo (the one that comes with the american vintage series) for 114euros (136$)and i have found a Gotoh vintage tremolo for less than half that price: 45euros(53$).........Are there any serious (materials e.t.c)differences between the two or in the case of the fender one i am paying for the brand name?????
