@jdoris - all anyone needs to look at is what is the cost of the repair and what options you have. If someone has not idea how long it will take to do a repair or won't give me a tight (do not exceed) range, I won't use him. There is a market for everything, and hourly rates are one way places can rip you off by not doing a job as quickly as possible. I find that if you pay by the job, you will get it done as efficiently as possible. For example, if you take your car in to a dealer for an oil change, the lowest guy on the totem pole will take care of it because they charge a fixed number of hours for that job, and he will be the cheapest for them. If you need a tune up or some diagnostic engine work, they will put the most experienced guy on it since he can get it done quickest, even though they will charge the same for it.
Different technicians have different levels of experience and it takes them different amounts of time to do a job. If they are learning and maybe only have done something once or twice, it is going to take them a lot longer.
I'd rather have the more expensive guy do the job quicker for the same price than the guy taking longer, even though his hourly rate is lower.
If a guy cuts your lawn, do you care how much he charges by the hour or how much the job costs? I don't care if he is super efficient or a slow poke as long as he does a nice job. Same exact thing.
