I know this fits on the standard Meade Tripod for 8-10", and I think it also fits the Giant Field Tripod (not sure though). Has the pegs that allow you to put the scope on the tripod without hunting for the bolt hole, and pegs to hold your controller in place. Plus, many eyepiece-holder cutouts. I can only find 3 of the original 6 screws that bolt it to the tripod, but these are simple screws that you could buy at Home Depot for 50 cents. Anyway it is quite secure with just the 3 screws.
$65 shipped, Paypal ok, USA and Canada. $10 additional international.
