I have a set of 12in digital's from HF, and a pair of 12in dial calipers that I tossed on an order from Midway one time, because they were on sale.
I like them both. Both are accurate, easy to read, and weren't expensive at all (I think when they are not on sale, the dial calipers from Midway would run about 35, where I got them for less than half that).
The digital calipers (6 or 12) will do you just fine.
