I have a 60CSx and a Colorado. I have had the 76CSx in the past as well.
There are a lot of things I really like about the Colorado, but if push comes to shove and I had to choose I think it would be the 60. The x (sirff) chip is a winner. A very stable platform that is proven. Granted it does not float, but you can remedy that with a zip lock or otter.
I say go for it if you can, you won't regret it and besides shiney and new alongside that beast that Tat uses would be such a contrast.
I'd really rather not cache, but I am helpless in the grip of my compulsion!
