Has anyone used Watchrepairusa.com?

They're located not far from me NW of Chicago. I have an Elgin 150 that needs servicing because it runs well but has started to stop from time to time. Their site says their starting quote for a "complete overhaul" is $79. Has anyone used them for a routine cleaning and oiling that didn't involve replacing any parts? I'd like to avoid sending it in and then hearing back that they want $250 or more to service it.
