In case anyone is interested, the Ark 1/144 Buran is available, now with more extensive tile decals:

The initial realease earlier this year included only minimal decals like the Anigrand kits. And prices were crazy - in the $60 to $80 range, certainly not justifiable.
From what I have seen it is a simplistic kit. I have no idea how accurate it is, but IIRC the real thing had smaller OMS fairings, no main engines, and the wing leading edges were less curved.
I have evil plans to convert one into the BTS-02 air breathing prototype. It was basically a Buran with four turbojets scabbed on the rear end, to permit conventional take-offs for initial airworthiness trials. I just need to source some 1/144 Tu-22 Blinder landing gear.

I do have Revell's enormous An-225 Mriya. Crud, I should have ordered two Buran!
