One word: HONESTY. Dave must be the most honest man in the business. I have known this guy for years and had worked both in my home and my previous business. This guy delivers what he says and will deal with you truthfully. He will tell you exactly what the problem is and give you all the options to save you gobs of money. He will not replace any part if he deems they're usable and can be fixed. He is fast and efficient. And did I tell you how HONEST he is? :)
