Possibly but you reallly need to take a look at them to see how well they are made , i have seen some cheap sets that amazed me that they could make them so well for the price and some that weren't fit to be used for tent pegs .
My test us to close the jaws and hold the set up to a light to see if there us a gap between the jaws – there should of course be no gap and i have seen some sets with splayed , twisted , bent and concave / convex ground jaws which will affect the accuracy of the calipers .
The electronics side is usually ok but some sets chew batteries as they don't really shut off they only turn the display off and these get relegated to the marking out gauge department and i take the batteries out between usage .
If the jaws are a little loose you can adjust them easily enough but also be aware the body of the caliper may not be ground parralel so you can get tight spots – if the calipers appear reasonably well made with a smooth ground appearance this usually isn't a problem .
