Keep you eyes on ebay for Thule – I picked up a full set of the posh Thule aero ones for my car (the OEM Alfa ones) for £50, brand new. Unlike every other set of bars I’ve had they don’t make any noise at motorway speeds.
Mind you, by the looks of those you’ve got roofrails already so bars are much simpler and no worries about damaging paint or the channels they’d sit in.
As for the bike bit, I’d be inclined to splash out a bit more for something better known. Mail-order can be a fair bit cheaper:

£40 will get you a Thule Freeride 530 if you’re buying two at the same time. I’d be inclined to pay the extra £20 tbh.
