Thanks canoedogs. Sometimes ignorance is bliss. Now I'll never get on DWs good side after spending more money on one of those.

EDIT: That looks like an awesome project for DSs cub scout troop. The kits look pretty expensive for that ($16 + $4.25 shipping is not bad for one but I can't afford to buy 10 -15 of them even at that price and popcorn sales were too low this year to get the troop to buy them). Any suggestions to improvise items or equipment. I am thinking along the lines of cutting my own tubes, say from plastic pipe, or using empty TP rolls for the coil tube (actually one kit uses the board itself for the coil wrap instead of an additional tube. That will save a little); buying electrical clips in bulk or simply using nails (it looks like a metal contact is all that is needed); buying the wire in bulk rolls if possible; cut boards from scrap lumber or from a large sheet of plywood; wire hangar for the tuning slide (actually the foxhole kits don't look like they need a tuning slide); #2 pencils shouldn't be a problem (buy a package and cut into shorter pieces). The earpieces and blued razor blades could be a problem. Any suggestions?
