I concur. We have a set of these and they've gone the same way. As @a1ex2001 says, it's from over heating. (At least that's what Circulon told me before they grudgingly replaced the largest of our pans under their warranty. To be fair, the replacement seems to be faring better).
I might be mistaken, but I think the copperstone pans mentioned by @HazardO are stocked by Tesco and are on offer in our local shop. If they're the same, I thought they looked decent.
We've had a full set for about 3 years now and they all look good as new.
