They are the mainstay, everybody knows of them, and they've got a great reputation so you sent it to the right place. Problem is, add in round trip shipping, and repair is more than a good used one. Granted I'm fortunate to be in area with lots for sale, but still.
I repair indicators (not commercially) and will say the Swiss ones, Alina, Compaq, B&S Tesa and Interapid - all part of Tesa (some of those brands were discontinued) and the other Swiss firm, Girod (did I miss any?) are in a league of their own. They really are made like Swiss watches, literally, and are amazingly durable.
I've got a Compaq on the bench at the moment, and it needs new ball bearings at the probe. i'm scared to think with the parts will cost....that alone often makes them often not worth repairing
. Mostly what they need is cleaning so I go with the farmers kill or cure approach lol
