They are all vastly different in prices between place's...use some one who does powdercoating of car parts tho if possible. I tried out a place who normaly does garden stuff and flag poles and the stuff came back crap, dirt still in places that he'd missed when shot blasting, no threaded parts masked off along with big drips hanging off some parts. Trouble is for what he does normaly that was acceptable. The place I use now do lots of car and motorbike parts so they are quite well clued up..every thing is masked off inc gasket surfaces on engine/gearbox parts and the finish is spot on.
