Since you mentioned Kinesis, Pro Bike Kit, Wiggle and probably some other online sellers have a - what looks to me to be a pretty nice - Crosslight 5T frame for around $280 or so (PBK free shipping, Wiggle ~$50). There's a couple of options for Kinesis cross forks, the alloy Crosslight for about $100 (excellent reputation) and the full carbonfiber Pure Cross (or something like that) which PBK has for around $160 shipped. I almost pulled the trigger w/ PBK because there is usually 10% off beyond that and w/ free shipping and their new points system, I think I could have gotten the frame and carbon fork for less than $450, delivered. This stuff looked pretty good to me and had geometry and other featurs I was looking for.
There are also 2010 JTS frame/forks available for around $400 and 2011 for $450 plus shipping, which can be $50-$100 from US sellers.
