Are you looking for used, or what? Rockler Woodworking has several different variants you can pick up. (They're over-priced if you ask me) Or, why not make one yourself? Its just a piece of hard material that screws to your router base.
I bought mine from Parts Express:

i made my own, cost me like $2 for a piece of acrylic, and different sized bits are no trouble, I just measure the radius of the hole from the outside of the bit to where i make my pivot point. I'm usually within 1/32 on my first shot. Close enough for government work.

Thanks,
Do you make new pivot point each time with different hole sizes or different bits?
Chris
Yeah, I just make a new pivot hole for each size speaker hole I have to make. I generally try to use the smallest bit I have for cutting, either the 1/4 or 3/8 just to keep the sawdust down.
Usually there is not that many different sized holes you need, so you can just keep reusing the pivot holes you have made.
Also for anything under 3.5" I just use a hole saw.

Please email me.

Is your router mounted to the table or is it hand operated?
I have the smaller Jasper Jig and they recommend use of the 1/4" up cutting spiral bits. That is the only bit you'll need.
