Having experience both in a computer repair shop and as a software developer, I can confidently say that The Eldest Geek is the most honest and fair computer repair shop you're likely to find in northern Virginia. If you're not a computer person and are looking for a shop that's going to use their knowledge to help you, and not cheat you, this is the place.
I recently had work done here on a Macbook Pro 15" Retina, through the repair several unexpected problems came up. Craig was easy to communicate with and provided consistent updates on the repair. With the issues that the computer had I would not have been surprised to have gotten a call informing me that the price would be doubling due to the amount of time that had been invested. Through my interactions with Craig and seeing his response to the problems I believe I got a better than normal view of how much integrity this shop is run with.
I'll be returning here for any future work I need done and wouldn't hesitate to advise others of the same.
