Depending on what you want to do with your bow.
I have a hogg-it with 2" pin guard originally it was for 3d but it soon found its way onto my hunting bow.

Any of the Spot Hoggs will do just about any job you want them too but as far as i am concerned the Hogg-It is the best and well worth the extra money.

You can pick them up for good prices on Archerytalk or you can give PW12 a buzz I know he sells them.
