1) Parts are expensive.  $75 for a few pots and some 555's?  

2) I've heard there is crosstalk between the VSS and RPM outputs

Plecan has three of these since day one and is a good freind.  Ain't

Although I wouldn't mind taking a look at his design to have a starting point.  Ideally I'd like to see the cost get down to $100 with parts and board.  How realistic that is is yet to be seen.  I'm getting a preliminary budget together as we speak.  Cross your fingers ;)
