Aero bars aren't necessarily more expensive than other carbon fiber handlebars. Of course there's a big difference in price between ALU and CF handblebars, and using CF allows for more aero shapes.
I have the 3T Aeronova's. What I like most about them is how comfortable they are for the various different hand/arm positions I can use (include IAB). I do wish they are slightly narrower at the hoods (they're about 2cm narrower than at the drops, 4cm would be ideal).
As far as actual aero gains, I'm guessing they're fairly minimal, but they can't hurt. To get the most gains I think you really need fully-internal wiring and integrated brakes.
