@Gary, thanks for the recommendations. I did look at your Zia grill but the old BPL price tag ($70) is a little out of my price range. I rarely make a fire when I backpack, so not at all sure how much I'd use a grill. But I have an opportunity coming up in October and thought I'd pick up an inexpensive one and see how it goes. Turns out Purcell Trench is closed for September.
Maybe I'll take your suggestion to go the DYI route for this first trip and, if it's something I can see myself doing more often, I'll "invest" in one of yours. :) Do you have a website where you currently sell them, or should I contact you directly?
