Local area engine shop/frame shop

[mbm]

Has anyone in Tacoma-Seattle area had any experience with either a local machine shop (engine rebuild) or collision/frame shop (frame replacement)?

some shops i heard about are:
Waterhouse
Cope Bros

and collision centers:
Collision Specialists
Precision Auto Body & Collision (these people seemed sketchy)

any feedback, suggestions, or experience would be appreciatted.
