I've thought about the investment in a BGE or Akorn as well.
As a new user and new entrant into grilling, you're much better off, IMO, starting off with a Weber.
Among other things, you're going to need want other accessories like tools, chimneys, thermometers, work tables, who knows what else. The price tag will add up quick, and if you're like me, your wife loves the finished product but starts to think a night out at a nice restaurant might have been cheaper for her.
Start with a Weber Kettle, you can never go wrong with it. It is easy to learn on, very forgiving of mistakes, adaptable to just about any method of grilling, smoking, or BBQ you want to try, and doesn't require the steep investment the ceramics will ask you to make.
Once you've acquired your stable of tools and accessories, if you decide you still need want an Akorn, you'll have a much better idea of what you're looking for by then.
