Locally owned MicroSeconds has been an Atlanta computer staple since 1992. The used computer sales and repair store caters to both individuals and small businesses. MicroSeconds specializes in lower-end systems -- usually priced between $200 and $600 -- and is especially well suited to tech experts; novices may have a harder time figuring out and finding what they want.
Bad Dog Computers
2575 Holcomb Bridge Road, 770-552-5570
This young store will necessitate a trek up Georgia 400, but it may be worth it. Bad Dog Computers has a small selection of used (and some new) computers, but the computers it stocks are often in impressively good shape and reasonably priced. The staff is helpful and patient. Bad Dog also repairs computers, installs home and office networks and builds custom computers from scratch.
