I got one of the One-Touch Golds in 18.5". Thing is a tank and I use it at least once a week. Take care of the grills and it has lasted me for the past 3 years without issue. Got the optional grill cover and the finish is still clean.
I've even done a few "low and slow" bbq's with it with some slight modifications to it (nothing permanent). It might be on the small side (the 18.5") but it's perfect for my household of one.
