To me it seems that the German alcohol stoves (google Spiritus Kocher) are good. Those guys have been making them for almost hundred years, and improved them until today. The Hpv stoves with 1000W burners looks good to me, and they are relatively cheap. To get a 2kW burner I would seriously consider cannibalising a two-burner unit. Then I would rebuild it so that both burners came close enough to each other to heat the same casserole or pan.
Simple (..on paper)!

PS: A single-burner 2kW Origo 1500, plus a single-burner Hpv-salsa seem to me to be a good combination for a serious cook.
After all, my boil-test showed that the Origo cooked 1/2 litre in 4:39min while the Optimus 111 did it in 3:45min after preheating. David reported on 20.9 that his Maxie burner took 5m 48s to boil the same amount.
What is left to check now, is how fast the Origo cooks 500ml when turned down to an all-blue flame.
