Hi Dino rover - something like the TOAKS Titanium 600ml pot or the Snowpeak Trek (various sizes) are good options, and both can be found on eBay. Also Massdrop.com regularly has Ti pots available, though not at present.
I have a Snowpeak 600ml pot, and have a couple of comments about Ti in general. They're great if you're just boiling water, but tend to burn on the bottom if you're cooking anything more substantial. Also they are not a great deal lighter than the much cheaper aluminium pots you can get at any outdoor store.
But I'm imagining a glazed "gotta have titanium" look in your eyes ... so I shall wish you well in finding your dream Ti pot

cheers
Peter
