I'm in need for a wire stripper and there are numerous discussions/comparisons here on the costly "pro" ones, but what suffices for hobby use? I'm staying away from the cheapest ones, assuming they'll break down in a couple of days, but there are a few claiming to be "automatic" and which I've read blogs and postings (not here) about from people who find them very nice:

Are they any good and do they last?
I made the mistake of buying a pair of them, they are utter rubbish, as they just rip rip the end of the wire off, rather than strip it.
I have tried adjusting the tension, but they go from not doing anything, to tearing the end off the wire, there is nothing in between.
