full set of rings could be
$150 - $200

polishing crank = $70 max

ignoring other issues that you find disturbing.... priceless.

it really depends on the cylinder bores.... if they are consistent and show no signs of longitudinal or uneven wear, they are OK to throw new rings on the piston and call it 'good enough'.

paying a shop to put new sleeves in or overbore it to the next reapair size is not worth the money. You should be able to find an engine for $500 - $850 without too much hassle.

re-sleeving costs over $500 (locally, at an esteemed shop)
