I'm with Jim on this, I have a Maverick and I like it and used it until I got used to where I like the temp at the lid, now I use one in the vent it works great.
I like old cast iron, check Goodwill places like that, old Wagner ware is nice Griswold or anything marked made in USA.
I got a nice Wagner number 3 at Goodwill for 4.00 the other day, estate sales are a good place to look also.
I was at Target looking at the Weber grills Saturday, and the wife walked up with the cart told one look at the jumbo joe I was looking at, threw it in the cart and said happy father's day!!
That might be a little on the high side , but I have that grill and I love it. It is super handy for small direct cooks. Another plus is it will run forever on a 20 # tank.
