I did not not mean to pick on computer geeks, you guys are right, they do way more then most peole think.
I do not know what the shops are like in your guys towns, but can judge from the dissapointmen what it's been like, mabey as a mechanic I have been fortunate to know good work and be able to read those mechanics who know and those who don't.
I would say try your local shop talk to the mechanic to see how knoledgable they are, and if something is wrong take it back and complain, be nice about it but let them know it's wrong, this way you can get it done properly and they know they screwed up, if you do not come back then they did a good job. If they continualy screw up (more then once) then go somewhere else, or like others learn to do it yourself.
