Here's something you don't see [from a company that's not going bankrupt] everyday: a "sales event" from Amazon and Right Start, where "select Bugaboo Cameleons" are 20% off. So instead of $859 or $899, they're just $719 or $749. [The all-denim is $789.]
Looking to see what has been "selected," it seems that they're all 2007 models, with either red or denim bases. This must be to make room [sic] for the new models, which have the solid, more Bee-like adjustable handle.
As a pusher of the OG Cameleon, I'd say the one thing that bugs about it is getting the screw-tight handle even on each side. And if it's torqued, the whole rig pulls to one side. Whether fixing that is worth $150-180 to you or not, only you can say.
