What size bike do you ride? If you're willing to buy from a shop around here, there may be a good deal (they're blowing out bikes). I like the shop but I have no business interest in them.
Remember about fit. Fit is extremely important. This is especially the case with a Lemond frame, which has a unique geometry.
If the Lemond fits you well, i.e. your saddle is mid-rail or positioned even further back, if you have a relatively normal length stem (100-120mm), then the Lemond geometry works for you (laid back seat post, longish top tube).
If your saddle is pushed forward, if you have a shorter stem, then you're riding the bike despite it not working for you. A more normal geometry frame will work as well or better.
For me, I'm the opposite of a Lemond type rider. I don't have long quads, I have short ones. I don't have a shorter torso, I have a longer one. I could get by on a Lemond but it would be far from ideal. If you're in that situation then a new bike makes sense. If the frame fits you great then you should get a new group for it.
Hope this helps,
