I disagree about buying a cheap one. I spent ~$200 five years ago and the internals are completely worn out.
I'm searching for one too. FYI Lowes has free assembly if you pay for delivery. BBQs are a beast of a box to transport.

That's what I'm leaning towards, don't really need the sideburner but I can't find a Broilking 4 burner without one.
