i forgot to mention i really don't like the way they mark up parts. it may be the standard way for shops but it seems a little deceptive. i think it would look a little better if their usuall rate was 80.00 per hour but they really needed 100.00 per hour to make it, just charge the 100.00 and leave the parts alone. it just seems a little shady even if it's the standad. some of the mark ups are huge. why would they do it if there wasn't some psychology involved in the price. i wouldn't feel bad about bringing in my own parts to anywhere, but i know most place would run you out on a rail. but hey, i'm not throwing stones. i work in one of the most crooked industries- health care. do you have insurance- one price, govt picking up the tab- another price, self pay- you my friend pay the most to help all those that can't. sorry not trying to get off topic. just out of curiosity what's the difference in price in the kits??
