I have a weber one touch silver. I could not justify the price of a performer, even off craigslist. I paid $20 for the OTS. I have some side tables already that are next to my grill and I use the side burner from my gas grill to light the charcoal. While a performer would be nice, I just couldn't justify the price.
That being said, my wife and I are on a pretty tight budget. If money didn't matter, I would go buy a brand new performer along with a brand new weber gasser and a brand new WSM. But we can't afford that.
