I have a very recent degree in Business, although marketing wasn't my strong point. In my opinion, using a domain name that isn't directly related to your business is a terrible idea. If you are Ron's Appliance, operating in Tulsa, I'd pay damn good money for ronsappliance.com...and tulsaappliance.com would be very low on my list of options. When people want to find your website, they are more likely to remember Ron's Appliance than some appliance repair company in Tulsa. Whatever you choose, choose wisely as you will likely have this domain for the remainder of the life of your business. The fewer amount of times you change domains, the better. I would put my money into ronsappliance.com(or a variation of that), then talk with someone experienced in SEO. They can tell/teach you how to establish your website so that you are at the top of the google, yahoo, etc search results. Take my input as you want...this is what I've found to be true for my business, and not necessarily true for your local market.
