Its up to individual really, as its your money.
Personally i have seen too much sh!t from GSF.
It also depends if you want to keep your car, if you do then i strongly recommend going to the main dealer.
The way i see it is, if you do it yourself, labour is free so why worry about paying extra for parts?

im gonna use proper vw parts now for my 16v, but i dont really care if my air filter isnt genuine vag you know what i mean.

my other golfs was a driver and a ryder so i didnt care as much if they died cos they were high mileage anyway
