Strategically located downtown, a short walk to the subway, 4G Data meets their commitments to estimate and repair PC hardware. I've taken several PCs to them over the years, usually after hours. Call them up during the day, make the arrangements, drop off the system at a time when other businesses have closed and you can be sure they'll take care of you with an honest estimate and/or repair. For example, one time the repair was not worth the effort. My ""bottom-line"" opinion: no pressure, no B.S., not free (they ARE in business), they listen to your needs, then deliver on time with no hidden gotchas.
