Well, the set you linked to is titanium, not stainless steel.
EDIT:I'm sorry, I have now re-interpretted your post as inquiring about the ti set,
and you're looking for a ss billy pot. Sorry.
I have the trek 900 titanium set, and it is pretty nice.
http://www.basegear.com/snow-peak-trek-900-titanium.html. I think the Trek 900 set is huge, especially for solo adventures, so it doesn't get out too much.
What sort of adventures will this be for? Solo trips or group trips? Cooking over fire, or gas? Cooking food inthe pot, or just boiling water?
I mostly boil water to reconstitute freeze-dried food. I'm not much of a backcountry gourmet. Anyhoo, my Regular lighter-weight setup us a small canister stove and the Snow Peak Trek 700 cookset,
http://www.basegear.com/snow-peak-trek-700-titanium.html. The stove and canister fit inside the 700 pot, and the pot has a lid.
I recently learned that my stainless steel SIGG bottle fits inside a Snow Peak 600 single-wall cup, so I may just go with that next time, and leave the canister stove at home.
The 600 single-wall cup is also available at basegear. I got mine from Campsaver. I got the bottle from Altrec, though I've seen them on the bay with free shipping, and I've recently found them locally.
If you want to got the ti route, I have really been happy with my Snow Peak stuff. They make a wide range of sizes for their pots and cups, so they should have something to suit just about everyone. Snow Peak also makes aluminum and stainless steel cooksets, but those seem to be harder to find.
