Don't skimp on a sight. Drop your pennies at coinstar or sell your old bowling ball on e-bay, just come up with a little extra money and buy a good sight. I also want to recomend the Spot-Hogg with .019 pins. For the best deal around try this place, the spot-hoggsaren't listed on the web site but he does sell them. Dan's a pretty nice guy andhelpful too.
