I totally get that they are pricey. For casual work around the house, most anything will do. I bring my cans on the road, so they have to be sturdy and secure. I envision having to refuel in a big ass hurry, in the dark and in bad weather. The J cans and a self-priming siphon are a lot of money, but man it's a system that just works well.
