Dave, I have a ti foil lid that I made for a SP 600 pot that I can send you. Here's a photo:
The handle is an "omega" of .062" ti rod, with a silicone tube covering. You can remove this handle simply by bending the rod on the underside.
I'll mail it to you, and I'll also include a couple pieces of scrap titanium foil so that you can make one you like better. If you gift me $5 to cover mailing costs, it's all yours. If this interests you, send me a PM and we will work out the details.
Edit--the lid weighs 6 grams
