We refited an Origo on our boat after the survey found that the propane system was not up to code. (Previous owner did a poor DIY, install.)
Having used propane on charters, and friends boats, and cruising all summer with our Origo, I would endorse the Origo. (I also am not affiliated with the company.) Ours was purchased second hand, was ten years old, and other than a good cleaning works faultlessly. We didn''t even need to replace the burner cannisters.
The big plus is when cruising, you can buy 24 hours cooking time of fuel, (3 litres) for around six bucks at any hardware store, throw it in your backpack, and keep walking. No heavy propane tanks to drag around.
