if your pocket is big enough buy a mitutoyo one i have a few of them and a couple of digies i use both types depending what im doingNever been a fan of digital kit. Call me an old fart,but I'm becoming a bit of a technophobe, (vast understatement), these days. Give me good old fashioned mechanical kit any day of the week.
u havent stated metric or imperial ??
They're metric, (I prefer using imperial, but beggars can't be choosers). Got my hands on three 150mm and one 300mm Tesa dial verniers. There is a Mitutoyo 300mm one too, but the gears are knacked in that one due to one of the gears springs working loose and getting snagged in the mech, so I've whipped the gears out and I'm just going to use that one as a general slip gauge. Never heard of the Tesa brand before though, so just wondered if it was decent kit. Couldn't turn them down whichever way for the price I got them for though. 
How much was the Tesa one?
Tesa dial calipers are made in Switzerland, of exactly the same parts used for Brown & Sharpe and Etalon calipers. If you're used to the top quality of old Tesa calipers, you may be disappointed in the new models. And, if you can get hold of an old model on eBay, grab it.
Been having a play with one of them, (it needed the dial rim reseating as the adjustment gear wasn't meshing with the dial), and it seems quite smooth in use. No slippage on the dial when you open/close it either, so it's not skipping teeth. Not tested the others as yet, but at least I know one's in good working order now.
