I have a 2000 21i and was thinking about putting perfect pass on it...any estimates of how much this would cost including installation? thanks

The perfect pass is about $1100 without installation. I would figure another $300-400 for installation depending where you go. If you have time, the install is pretty easy and you could save yourself that 300-400.

im not really gifted when it comes to installing anything no matter what it is but I guess I could give it a shot...

I replaced the paddlewheel housing unit and it was fairly easy. But everything else that comes with it seems to be very difficult for the average guy to install.

1400.00 Installed is about a average price

Initially the box of parts can look intimidating, but if you read the instructions several times and lay the parts out as you do it I think you will find that its not really that difficult.
