The egg is a fine piece of equipment, but you'll see the capabilities of the Cookshack far exceed the Egg, though your not comparing apples to apples.
Even the CookShack website is packed with info, and their forum is very good.
BTW, the Electric Cookshack turns out such good consistent smoked meat, that it's banned in BBQ comps. Cookshack came out with the Fast Eddy model that takes charcoal/pellets.
The Egg is good, no doubt about it, in fact a 90 buck Weber turns out killer BBQ.
