I too am willing to prepay for two kits. The weatherband option sounds interesting, but I would be happy with just FM. If you are still looking for extra input ideas -- how about an input for an external dimmer signal? My factory (Toyota) headunit's display would adjust when the dash lights were adjusted. It would be nice to restore that feature. Just a thought ... thanks for taking on this project. I will dust off my soldering iron in anticipation.

P.S. If you decide to create a full blown police scanner model I would be willing to pay even more (say $250), and still prepay two tuner plus shipping.
