Motor mounts were done on my car at 80k miles (did it preemptively when transmission was out). One of them was in pretty bad shape.
Obviously RB job in LA will be cheaper than in SF (like everything else relative to the highest cost metro area in the US). The reputable shops all charge around the same amount here. Even if there were price differentials, I would only trust 2 places in the Bay Area to do the work.
As far as the bolts, as mentioned Carbahn/Dinan have been satisfied with performance of OEM ones, and not sure why re-usable bolts are necessary unless techs are less skilled in RB installs given the anticipated engine life. Dinan has been very satisfied with the performance of the stock ones (none have broken and none were torqued improperly in the hundreds they've done for race and street cars), and not going to argue with the very same people who have the most extensive engine building experience in the US for BMWs. You could specify any bearing/bolt combination and they would have installed it....BUT not provided the 2 yr warranty.
Bearing issues have been seen on both the tin/aluminum as well as the lead/copper. It's true that I didn't need a RB job and that they would have lasted to about 130k-150k miles (the service life of an M engine). While some may state that it's excessive wear for 90k or 130k miles, but kind of irrelevant point if engine doesn't last beyond that no matter what bearings are in there.

ARP bolts (racing standard for decades) don't have this issue.
Price for the service was $2000, so you were overcharged by 50%.
I bet you paid a fortune for the BMW OEM bolts.
I did my RBs at 180k miles (twice your mileage) at BE/Auto Talent. Wear was at the seams with exposed copper. Blackstone said my copper/lead was great, using junk BMW 10w60 oil at 15k mile intervals.
Piece of mind is a good thing, but other maintenance bills will pile up after 80k miles.
M3 e9x RB service is cheaper than a brake job.
