I need to buy some LEDs for my mod and thought Fry's prices are ridiculous ($2+ for one LED) and I know you can find them online for better deals. So I've heard of eBay stores pratically giving them out and was wondering if anyone has any good experience with one over the other? Or an actual online store? Also on the side, I can't quite imagine the difference between 3500 mcd and 5000 mcd. If anyone could explain this in terms of case lighting I would be very thankful.
