Don't get me wrong chaps, i'm all for saving a shed load of money on audi parts and yes some B7 oe parts are just bonkers, i'm also allways open to a diy project etc.
On the subject of grilles though i think the OE rs4 grille route is byfar the best plan.
So downsides.
They are not the cheapest item around and also very few good ones to be found in used format.
Plus points though,
they are a straight hassle free fit , they are an OE part so decent quality and they come in several surround colour/finish and most importantly they look spot on.
As much as i love a good project and you guys do top stuff with rs4 alternatives , for me the OE rs4 b7 grille is byfar the only real option.
just my input chaps on a wet old sunday evening.
