so is it a good idea?

im about to get a washburn x10 (has wammybar) then my freind tells me it would be pointless because whenever i used hte wammy bar it would go right out of tune!

but its not like i need to use the wammy bar so i i think im still gunna get it.

but do you think it would be possible to add some sort of tuner locks or floyd rose tremelo bridge, i dont know a whole lot about those things, nun the less actualy ADDING them to a guitar.... so whats your take? is it an easy ad? like if i got someone profesionaly to do it .... if thats possible, or would it be a magor investement to add one?
