Vibration in engine- help!

I checked the local stores on-line and nobody has a balancer, NAPA does not even list one.
Jegs lists one but notes it has 6 holes evenly spaced- wrong!
Summit has one listed for the least at $208, but it will not ship until 9/9/2010.

I'll check mine tomorrow to make sure its bad.
I had no idea these would be this much, or this difficult to get.
Check 440 Source and get one of their chrome cheapo ones...it works for me...89 bucks
