I have one! I think it's the 28". I like it a lot more now that I've been using it more often. In-laws bought it as a wedding present and it sat all winter as our deck isn't covered. I wasn't interested in cooking outside then lol But I spent one day this spring seasoning it and watching dozens of people use it in youtube tutorials so I could get a better idea how to use it. I'm getting there!
I don't think I've been cleaning it right, after use, but I'm going to try General's method of cleaning next time. I've used it for chicken, steak, fajitas, salmon, breakfast (I wasn't a fan of scrambled eggs on there though! Fried eggs all the way) It's been a great gift more recently as we're trying to sell the house so I've been trying to cook outside as much as possible to keep smells and mess out of the kitchen. If we camped (and we plan to once we buy a house with room to keep a camper), I'd absolutely invest in a 22" tabletop. It'd be perfect for that.
I've also found a small inventory of accessories at Wal-Mart.
