Honu,
I have mixed feelings on the Baja. It is built really well (everyone knows that... It is a SnowPeak). I didn't really pay super close attention to fuel usage because I also used the canisters for other things like the torch to start fires. I also didn't really feel like I had a ton of control over the flame. It put out a decent amount of heat... But, I struggled getting the flame low enough to simmer things. So, I don't know if two would have made me happy or not. And While I really like the snow Peak IGT set-up... I have always been a little conflicted about it. For one, I don't really like having to carry all the canisters, parts, etc. I also like a grill with a cover. I have always used either my Weber Smokey Joe or Go Anywhere. Neither of which are convenient to use with the IGT set-up. About the only hing I do like about the Snow Peak IGT set-up is the quality and craftsmanship, and L-shape configuration that brings everyone around for a more community style cooking experience. So, since I can't get what I want out of the SnowPeak IGT, I am working on designing something similar that offers more flexibility to use non-SnowPeak products. It will hopefully have adjustable legs so I wont need different legs to set up for different needs, fold up smaller, Etc.
I am headed camping the next two weekends. So, the partner will get a good break-in and I will know if I have finally ended my search. Then I will have a hard look at my grill set-up and decide if I will stay true to my charcoal roots... or make the switch to a good quality gas grill.....
Now to figure out exactly which nut inserts I need to work with the SS adjuster Spresso showed....
