Shawn: If you want the cheapest shipping, that would probably be by boat. Will take 1 to 2 months for you to get your order.
My order would be (assuming all colors are available):
Blue: 6
Green: 4
Red: 4
Orange: 4
Now, if orange were not available, I'd get 4 clear. If any other color were not available, I guess I''d have to re-think ALL my color choices.
As for switches, I guess it depends on price, but I don't HAVE to have the switches.
