With the Kreg jigs, do you use their screws exclusively? 
I do, they do a better job of pulling the pieces together in my experience and they seat very well into the pocket, whereas the head on a wood screw isn't flat underneath and will drive through.   
Thanks, LC. I think I would have to play around with different screws, just because it is my nature. 
A couple more alternatives - 
Harbor Freight.

With a 20% off coupon, it is $55. They have been running 25% off coupons lately too.
The $200 porter cable one seems cool, it automatically adjusts to the thickness of the wood, but it is $200ish
