Hi JMan...for $50 I don't think you can go wrong. Looks like a pretty solid pit for that price, and according to the link in your first post, they go for $900 brand new, so that seems like a heck of a deal. But you're right about capacity. Doesn't look like you could get enough meat in it at one time to feed a big crowd. It's a little hard for me to tell from that 2nd photo...are those rib racks, or some kind of 2nd shelf/grate? Either would increase your capacity. If that's not a 2nd grate, for a few bucks, you could probably fabricate one that would basically double the capacity.
