I have Pagid RS 4.2.1 with standard discs and they seem to be holding out very well, although more expensive - also try Ferrodo DS2500's.
Unless you are killing your car everywhere, your pads should last longer. Try not to use the brakes like the old, shall remain nameless, 11000 posts of crap, on Scoobynet one who has managed at least 60,000 miles on his first set, not even half worn, runs on standard unleaded, hates modifications...some may knwo who I mean - starts an argument inside a paper bag.
Try phonign Alyn @ AS Performance for a good price on the Pagids - he is VERY helpful and loads of people use him.
