Hi Zane,
I've checked out the TV scopes. They're nice. You only have to look at what the STL11k can do with the new TV127is -

Very nice wide field work. The prices are reasonable. I'd like something that can handle the STL11k considering I've just placed an order for one. I should have it by late November.
The Tak180 is a very good option (I have thought about buying one), I'm interested to hear your collimation woes. Canberra astrophotograper - Steve Crouch has produced some sensational images with a 180+STL11k -

Its a difficult call to make. There are not many scopes on the market that can handle the STL11k wide field. Sure you have some RC's and highend refractors. Most SCT's are out of the question, even with a 6.3 or 3.3 F/R. Though I'm interested to try it out on my C11 with GEG configured for F/4 mode. The 80mm F/R lens on the GEG should reduce vignetting and considering it was designed for 35mm film size frames, it may work ok with the STL11k. Will be sure to keep you posted.
