It's interesting you found the 2003 Lemond too rigid... which model did you try? The Zurich which for 2003 is a steel/carbon hybrid should be anything but rigid. I ride the 2002 Zurich, which is all steel, and find it to be a flexible ride.

I would suggest you stay away from Aluminum bikes if you don't want a rigid, harse ride. You need to consider carbon, Ti or steel. I wouldn't shy away from a steel bike. New steel bikes are very light weight and very comfortable to ride. Steel is also durable - just like Ti but only better!

AND and can't emphasize this enough and lord knows this forum is full of the same discussion but get a bike fitting before buying the bike. Standover is no indication of bike fit. There are so many other measurement even more improvement, reach being one. Every bike is different so you need to be sized on your bike of choice. If your legs are long but torso and arms short, you might be a candidate for a WSD model but do not assume just because you are a women WSD bikes are for you.

Good luck, take your time. Don't rush your decision. Be informed, research, research, research.
