I've got most of the circuit designed already, total parts cost is going to be around $15 for the first one (already have most of the parts laying around), closer to $30 for more, I'll probably be willing to sell these for $75 with core (need the connector) preassembled, $50 for a kit with etched circuit board... I'm a highschool student, so really, I'm happy with minimum wage, and I'll be able to get these soldered in less than an hour easily. I'll even post the schematic and source code when I'm done so you can build your own.

I can add some more features too, who would like to have a temp sensor that will use the cruise to raise the idle slightly when its cold so you don't have to hold down the gas?

I'm using a 40-pin PIC microcontroller because I have them laying around, so there are many unused IO pins, how about connecting them all to solder points, so you can use them for anything you want? I'd be willing to custom program anything you want for $25 or less...

I'm doing this for myself as well, so the first one pays for the hours of design work...everything else is just a bonus for me..
