I had the Double Boiler for a couple years and found all I used 99% of the time was the big pot of the two. It was pretty much a Soloist without all the fancy doodads <img src="/forums/images/graemlins/wink.gif" alt="" />
The little pot was ok, but really too small to use. Probably the best thing GSI did was redesign the handle. On the original Double Boiler the handles were BAD. They liked to flop.

Personally I would recommend a Ti or steel cup instead of the small part of the old style double boiler. More stable for boiling a cup of water.

Now, if one wanted it for snow melting? Then yes, a good buy!
