I do not have a BGE but would like to own one.
That said the cost difference alone is a pretty big deal since you can get both an Akorn and a 22 WSM and still come in cheaper than the two larger BGE.
If your set on a ceramic Costco sells the Vision brand komado that is somewhat more affordable than a BGE however doesn't look to have quite the same level of production value behind it.
Me personally I have a OTS, the bullet, and in the process of building a mini-WSM. I have a 10 yr old off brand gasser that's on it's last legs and as sooner as the burners rust through it's going in the garbage. I am up in the air between getting a Weber Genesis gasser and a BGE, given that price wise it'll be fairly close.
And apologies as this rambling response really has no bearing for the OP.
