I was very tempted to buy a pair yesterday, then I reminded myself I have four pairs of digital calipers already. Then decided I really didn't need the 33 draw cabinet either 
At least I managed to get a very nice 'wixey-type' angle gauge from CPC, with built in (properly adjustable and quite sensitive) spirit level and a very handy absolute function, two features not on the typical gauges, and less than a tenner.
