Yep. Seen it. But it's on a "permanent" setup and he's got a real good shed around it with roll off roof to cut the wind. I think 12" might be pushing it for a "going away" set up.

It has suffered about 4 tubes so far, and the latest reincarnation is a truss C/F tube.
You capable of fabricating the tube? If so, simply purchase the optics and do the rest yourself. GSO optics are great, I have them in the 16" and had them in an 8" a while back. Can't go wrong, just make sure you don't skimp on the focuser.

Thanks Gary. Yeah the idea of buying the optics crossed my mind. But at this stage I think buying one already made up might be fitting my budget better. By the time I'm getting a tube, a mirror cell and all the material not sure if I can match $1k or under.
