QBC chainrings are cheap and come in all tooth counts and modern BCDs. They don't look particularly attractive, but they function and wear decently. Although my 110 and 130mm rings have fit properly, I had to use my Dremel tool to make a 135mm QBC ring seat properly onto a Campy Chorus spider. Genuine Campy rings always fit properly without milling.
I use SRAM chains exclusively and think they are great, but this is not a universally-held opinion.
KoolStop brake pads outperform Campys and greatly outperform Shimanos, particularly on older, less-leveraged brake systems.
