I think we had this conversation not too long ago, but since i am here, I may as well throw in my $.22 worth
Thanks to Craig's List I have two Large Eggs and a Small. I also have to WSMs (One bought new and one from eBay). I figured out that my average cost for my Large Eggs is $250 and the average cost for my WSMs is $130, so while the Egg is still more expensive, by being patient you can reduce the cost difference tremendously.
However, even if I bought the Eggs new I would still vote for the Egg. The versatility and the stability are what sold me. As already mentioned, I can grill at "normal temps", I can grill at lava temps, I can cook low and slow and I can bake. Once the Egg is up to temp, it just doesn't move temp regardless of rain, snow, wind or outside temperature, so considering that I can have problems with all of those in the same day around here, that part alone is a big advantage. A friend from another forum said it best...

they cost more than they should, but they're worth more than they cost! </div></BLOCKQUOTE>
I'm not giving up my WSMs (sorry, Harbormaster
) but my day to day cooker right now is the Egg.
