My friend's beloved Mac died. To buy a new one would have cost $1,500; a used one, $500. After seeing the good reviews here, I took it into Allen. He did a thorough diagnostic and confirmed what I suspected - the hard drive had died and the system needed more RAM.
Working in IT myself, I figured to get a new hard drive, install a new O/S on it and add another gig of RAM would be about $300. Allen did it for around half that, and had the computer ready THAT SAME DAY.
This kind of service is unheard of these days, especially in computer repair. Many of the repair shops out there are criminal "chop shops" who will rip you off as much as you can. Allen is a shining exception to this rule. I highly recommend him for anyone looking for fast, honest and fairly priced service.
Note that when you go there, he's at the back of a jewelry store. He doesn't have a fancy storefront, so he's able to pass the savings on to you!
