Bring a broken or outdated computer to some of those big-box computer stores and you'll get one of two responses from the sales staff: geek supremacism or complete ignorance. And no matter which response they give you, they'll always try to sell you a new machine. Not in the mood--or the salary range--for that, we went to the Little Shop of Hardware and brought along our ancient IBM laptop, which was so low on RAM it could've landed the starring role in Memento. With enduring patience, the digital denizens of Hampden dug through a bucketful of chips till they found one that worked on our old computer. Little Shop of Hardware will also sell you equipment for home tinkering, do house calls, or even build you a PC from scratch. And you always know what you can expect from these guys: clear information, polite service, and prompt repairs.
