I have access to a Meade LX200 telescope.

I just need to figure out how to use it and attach my a300 to it. I'm taking a shot in the dark asking this here but, which T-Mount would work on it. Would this adorama one work? or this Opteka at amazon? I know I read somewhere that don got a meade telescope so he might know. Are these pretty standard or do they only fit certain types of telescopes?
