-Its essentially part of a system with interchangeable 'bits' for different aplications. There are also a good number of second-hand bits available as well as third party gizmos made specifically for the TSA series.
-You can actually find out how much it costs here. I never have and never will by anything from the Vixen dealer as long as he prices things at $1500-$3000! Daft.
And last but not least (and assuming the price difference is not an issue):
-The TSA's optics are famous for their resolution and colour correction. If you have found a report that shows the Takahashi offering measurably or noticably, superior resolution, to the Vixen, that SHOULD be the end of it! 
Its a no-brainer. |
You have your shops mixed up Peter, astro optical have price ranges not myastroshop. That said I would choose the Tak over the vixen simply because it is a known even if the adaptors were going to take ages to get and cost an arm and leg to buy.
The fourth element in the vixen is seperate from the triplet cell and is only there to flatten the field for AP, it does not have any colour correction function as far as I am aware. I was thinking of buying this scope last year and asked a lot of questions. I imagine that will present its own problems if you want to use a focal reducer, not too sure though. If it is being bought to take pics I think at F7.7 I would probably look at a GSO RC instead as aperture rules.
