QMX Online have for sale a perfect replica of the USS Enterprise NCC-1701-D at 1:850 scale, which measures over 29 inches long and over 6 inches high.
It comes with a full set of working lights, sound effects and shuttles nestled within its huge shuttle bay waiting for launch.
It has a mirrored base and a name plaque which can be customised and the whole thing is packaged into a transport crate that Paramount would have used to transport its filming model.
Actually, the ship is modelled on the studio prop so therefor is highly accurate and the detail is beyond imagination.
There is a waiting list and this beauty will set you back a cool $10,000 USD, plus any shipping costs.
For all you Movie fans, these guys also build a highly detailed 1:350 scale USS Enterprise NCC-1701 Refit or A, which is over 34 inches long, but orders for this are currently suspended due to workloads…cost of this, my favourite ship, is $7000 USD
