I bought that exact one on Ebay two Octobers ago for $186. I got lucky and found the plastic case from another seller for $17.88 shipped. I HATE that "handy contractors bag" as it lets everything bash itself to death, though it is "handy" for keeping plumbing stuff in for travel.
You will find that kit to be VERY handy and worthwhile--and half the cost of the FUEL set.
I never clicked on the product details, does the CPO kit have the 2601/2650 or 2606/2656? Either way not a terrible deal. I was happy to get it recon for $140
