Big Green Egg find(?)

If you get a nice price on it I would get it all.
The platesetter is for indirect cooking,the V-rack is for roasts and ribs (I think) and the Nomex is a gasket.

The v- rack is a wire rack which, turned one way cradles meat up off the grate. When turned upside down can be used as a rib rack. The nomex gasket is a higher heat replacement gasket between the lid and bottom. The plate setter is used for indirect cooking and is a must.

$400 with those accessories, provided there are no cracks is a good, but not great deal.

With the guy stating those additions, he may know what he has. Does it have a nest? That would add another $150 to the price of a new one. The medium I bought was 10 years old but in like new condition, with nest, side tables and cast iron top daisy wheel. The guy mostly just wanted to get it off his patio and was asking $100, so I said "Hmmm, let me think about it...OK I'LL TAKE IT!" I'd offer $250 and go up to $300, but it really depends how badly you want it.
These are fantastic cookers, and if narrowed down at gunpoint to only being allowed one cooker, I'd have to chose a BGE type cooker because they're so darned versatile.
