I have several of the Uticas, they can be had for much less on ebay if you don't mind calibrating them yourself which you'll need a good torch wrench to do, I use a Sears automotive type for that. I bought one batch of 6 for $28 shipped and got 1 good one out of them, the others need to be rebuilt, but I won't spend the money on em. I have TS30, TS35 and TS100, all cost less than $30 each.
