the shop honed the cylinder which had the stuck piston, yes?
honed to minimum clean-up
how much was that?

what is the actual value of the bore diameter, both cylinders.
Is there taper to the bore?
The shop you're using should be able to tell you.

it's not just a BMW thing.
but yes, pistons are damn expensive.
That alternative, smokey R90 engine is an attractive option.
