Breakout boards, wireless stuff, micro controllers, MMC/SD Card stuff, GPS, LEDs, actually, how about EVERYTHING? The cool thing about Sparkfun is that they have all sorts of stuff at reasonable prices. The problem is if I wanted to get a couple chips and LEDs for $5, I'll need to fork out $10 for shipping and wait two weeks. An UK reseller will be great!
