Sig is replacing their 2000 with the 2200MR I believe, supposed to be a 5% or 10% improvement over the 2000 in ranging ability plus has a smaller mill/moa reticle for the same MSRP. Check out the "Sig Kilo 2400 with applied ballistics" thread
There is a guy on here that is selling the 2200 and the2400 new if anybody is interested I can look up what the price quotas he gave me.
