I own the primus eta lite stove, I bought this system because of how well made primus makes its gear. A lot of thought is put into there products. They're not the lightest but if durability is your main concern primus is a great company.
Can we get some pictures of the bottom heat exchanger?
JamesBrownI have an ETA Lite and had the same question. After watching the product video, this pot does not have the same triangular base connector as the ETA Lite, but rather a large circular opening inside the peripheral heat exchange baffles so you could use most canister stoves. I believe you can still use the ETA Lite stove if you want - you'd just have to use the the three screw posts (included with the ETA Lite, on the handle) so this pot can sit on top.
