Toseek do a pretty decent Aeronova copy, bought three for myself and another for a mate, and no worries. If you're not familiar with the Aeronova, it's a revelation - 3T pretty much defined how aero drop bar tops should be shaped with this.
Only caveat I'd suggest, is if you buy $50 carbon bars, just try to break them before you ride. If you can't bust them by hand no matter how hard you try, they'll hold up IMO.
