Crawdaddy, I should have added that I also have a mini. I like the medium because it's really not much bigger than the small but is much quicker to load and cook on than the large or XL. My mother has a small and it's good but I can do a pizza on my medium and I don't think I could do one on the small. Basically my thinking is that if you want a combo, get the second to be two sizes smaller than the your primary cooker. If I had a large, I'd get the small; if I had an XL I'd get the medium; if I had a medium, I'd get the mini. If the two or only one size apart, I think you would use the largest size all the time (except when you need two) because "there's not that much difference and I might just need that extra space"
