Derek, you won't be disappointed with the BGG-3. I bought one after camping with a buddy that had one. I bought the two burner griddle, and you can cook as large a breakfast as you want. I think you're on the right track with the larger stove, rather than the first one you posted. I know they list the combo as close to 150 pounds on the web, but I don't think its nearly that heavy. I can easily carry the stove with bbq box attached, and the griddle is less than 30 pounds.
I think I was right around $350 US with free shipping from a major online retailer for the stove, griddle and carry bags.
