To add my second lot

Ay-Up lights – just done the upgrade to new light units for silly cheap
Santa Cruz Heckler
Hope BB outlasted anything else
Camel Back Havoc – got disappointed that a zip had failed then i realised it was about 5 years old

+1 for Superstar wheel sets (hubs and rims) as well as SS seat posts.

My Superstar wheels – rebadged Alex Rims, generic cartridge bearing hubs, laced up with Black Sapim spokes, all for well under £200, and a fair bit lighter than the wheels which came off my Boardman.

Superstar lock-on grips.

Funn 700mm bars bought from CRC for a tenner recently.

White Charge Spoon bought from Wiggle for £14 a couple of weeks ago – nice perch.

Bottom end SRAM/Shimano stuff that just works, and costs so much less than XTR/X0/XX

Halo Knobbler mud tyres – around £12 each when I bought them, heavy but unstoppable in winter Swinley mud.
