Changing bridge to tremolo

[EnochianVerbalInstrument]

Hi guys, just a question

I'm thinking of changing my guitar's bridge (sa 120) to a trem bridge (maybe the zr trem). I'm not sure if this is true, but I heard that a bit of routing would be needed to do that.

How much would it cost roughly to do such? Cos if it's really costly then I might as well get a new guitar with one installed. Then again a bit sayang to my guitar go cos this is my first guitar.

I rather not keep more than 2 and I am already eyeing another model as my second guitar.
