Paid a fiver my mine just to use the readout to repair a scale, they were ok some years back dont know about now.
Careful of some of the chinky ones, they dont always go back to zero or register some ficticious reading. Constant zero reset every time used like these http://cgi.ebay.co.uk/6-150mm-Digita...item2305d18ad9
These are ok large readout.
Mitutoyo are the best, i have 5 and two analogue. Wish they would make them drop proof inc the newer dearer coolant proof ones.
At least the price has dropped since first introduced.
