I used bulb number 74 from superbrightleds.com, got them for $1.00 each, I had an order of 150 of them, so the prices went down quite a bit. otherwise i think they are like 1.29 or something each. you only need 5. I bought 10, so I have $5.00 left over, I will let go for $5.00 plus $1.00 shipping (still $4.00 cheaper then superbright, if you were buying with 100 more!).
As for the resistors, they are $5.00 for 100, thats $0.05 each! way better then almost $0.20 each at Radio Shack. Anyone who got in on the GB will get resistors.
