What Mike, said. If it doesn't have a thermometer and the other things, it is a pre-2009 model. Whether the price is great or just ok depends on YOUR perspective. But if it is pre-2009, think about what you would have to pay and do to add a thermo, a heat sheild (that's a good thing), or get a larger water pan (Brinkmann - $15). Some prefer the smaller water pan (shrug), don't care about the heat shield or the thermometer.
I got my 2010 18.5 last year new, in box, for $200 and considered it a great deal. You may occasionally find a better bargain, but not often.
