I had bavrest rebuild my m42 AFM and it cost me $135+shipping there. Im very happy with the work they did, and it looks like new! the plastic cover for the springs/gizmos got cracked up a bit when they removed it so theres a little extra silicon on the one corner but its a very minor detail - I tried removing one of these covers myself at home and its very hard so I don't blame them.
Granted it took about 3.5 weeks form the time I mailed it off to when I got it back, so I recommend having a spare AFM. The car runs great now and throttle response is much about as good as it could be I think. If you are having AFR problems Id start with the 30 year old AFM, even if it works pretty good I bet its still flatspotting at some areas in its working band giving the computer bad air flow readings and causing burps in your powerband.
Highly recommended.
