I’ve been doing a little research on lightweight backpacking equipment and ran across this great little tri-fuel system. It burns alcohol, wood, and esbit (fuel tabs). It’s a little expensive but the price seems fair for the flexibility and materials.
I’ve been on the lookout for a good alcohol stove and I think I found it this morning on pathlesspedaled.com. It’s super lightweight and even has an optional wind screen. The stove is a Clickstand. You may also want to get a burner to go with the stove. Total package looks about $50.
