I just got my Fat Track calipers. $30 online; they work great. I need to get better at the skinfold but my avg. thusfar is about 14-15% and seems to be repeatible.
The calipers can store 3 profiles for M/F and your age. The measurements can be done by yourself; for men its probably easier lacking a tricep measurement. Its chest, stomach area (superilliac?), and thigh. The women do the tricep instead of the chest I think. Once the measurement is done, based on the profile it cranks out a BF% for you without you having to do the formulas. They are apparently accurate within 1mm which is identical to Lange calipers.
