ECB stands for El Cheapo Brinkman. Brinkman is a brand of smokers that are much less expensive than many other brands. The propane fired Brinkman would be a gas ECB. I ordered a propane-fired bullet Brinkman for about $120. The same in any other brand is closer to $250 or $300. I've seen posts about mods to the charcoal ECB that improve performance and wondered if any are needed on the gas model.
