I *HIGHLY* reccommend Scott Malcolm at Malcolm Technical Support in Colville, WA. He was working in service at Icom America the entire time the IC-735 was in production. His rates are reasonable, his work is first class, and his turn around time is pretty darned quick.
Look at the reviews MTS gets at: http://www.eham.net/reviews/detail/1786

Scott has repaired three different Icom rigs for me and I've been extremely pleased each time.
