What cookset do you recommend for this stove?
If the lid/pot that comes with it isn't enough, and depending on if you're going to be using it for solo or a couple people, I would look at the Snow Peak titanium pots. Start with the Trek 700, then the Trek 900, and if that's not quite big enough, go to the Trek 1400. This stove will also nest into both the 900 and 1400 nicely.
If you're interested in keeping an all Optimus kit, here's a link to what they offer as well.
Still using my old banged up Sigg kit.. Comes with a windscreen that holds the pots up. I don't imagine they make them now-- try Ebay.
