im not sure if this is the write forum or whatever but o well.

i swapped a strat with my friend (my old electro acoustic for his strat) that needed fixing up

i took it to the shop and to have a new bridge fitted (13quid for new bridge) a new set of machine heads fitted (10 quid a set ) and a tremelo bar (5 quid for new bar) its gunna cost about 35 quid for them to fit the parts.

is it worth the money or am i being ripped off
fit the parts yourself. 35 quid (is that about double USDs?) is a ripoff for installation, but the parts are basically the right price.
i mean 35 all together ..including the parts and i havnt been playin for long and dont have much knowledge on replacing parts
