Query: Bottom warped

I've used this pan for about 2 years and am now searching for an alternative. It has gotten so warped that it no longer heats evenly across the bottom. We like to pan sear steaks and chops, and it's a real hassle when the pan does not heat evenly. We use an LG electric glass cooktop and have not seen this problem with other pots or pans. The warping began about 6 months in and has gotten progressively worse. I think that the problem is that the pan is the same thickness (or thinness) all over. That makes it very lightweight, but also keeps it from sitting flat on the stove. I hope one with a thicker bottom will work better and for longer. Sorry that I could not be more positive.p.s. When they say wash by hand, they mean it. The dishwasher leaves ugly spots all over the surface. Not a factor for us, but if you like pretty pots, something to consider.
