I have to agree with Jake. It's way too easy for a person to just go to the SPAD website, print out the directions for building one, and put one together for about $6.00. There's not too many people who don't know about SPADs, and if someone doesn't know about them, they will find out pretty quickly from someone who does. A lot of clubs encourage newcomers to start out with a SPAD simply because they are cheap, nearly indestructable, and if you do wreck one, it only takes an hour or two to fix it or to build a new one.

Good luck on your endeavor to sell SPADs, but in all honesty, I think you're wasting your time.
