Flip mirrors

Dear All,

Can anyone recommend a good flip mirror system please ? I presume I want a
2" one as I have several 2" EPs. I'd like to be able to use it with my dSLR
as well as the Meade DSI Pro and Toucam Pro II. I am hankering after the Van
SLyke Engineering Slider 2, but it's expensive.....

The main question I have, is will a flip mirror work with an f3.3 focal
reducer in the path as well, or will there not be enough back focus ? Scope
is a Meade LX200 GPS 10"

Thanks !
