i suppose I could buy one set every other month or so until I have them all. Ground and sky traffic...now that's a much needed deal. AS far as pricing again ... I realize the work and agree the price is set at a good level. The overall quality is awesome. But I'm one of those frugal cheap guys :) I'm not afraid to admit it.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
