Hey guys, if you want a huge selection of different sizes, shapes, and cuts go to a semiconductor or a computer place that sells hard drives. Here in San Jose, there are quite a few, but all hard drives and most other computer peripherals are sent in boxes with massive amounts of foam (ie egg crate etc.) most places save it for when they have to ship products back, and the stuff just seems to build up...so they are more than happy to have you take it for free. Just a suggestion, it works for me!
