I have a Japan made 2006 and I had my gearbox bearings replaced. Cost me £324, all inclusive, by a gearbox specialist, and I am glad I had it done. Bearing didn't start to rumble until 90K. First price I got, from a local garage with an ex-Honda mechanic on the staff, was £1100.
Basically, what I am saying, is, if it was me I would be swayed towards the one that has been done, all else equal.
