I'm on the verge of ordering the Scorpion. If I do, I'll be sure and post how it runs on household NG. But I'm also planning to do quick connects so that I can cycle in propane for boro and use the NG for soft work. When I do boro, my Cricket already uses all the NG I can give it and I have lots more oxy that I could use. So it'll be interesting to cycle in the Scorpion. There's like to be a standard purple Cricket for sale soon
