I love the ship, the NX-01 is my favorite ship in Trek. I love how it feels like a ship, that claustrophobic working environment you don't get on the Hilton ships. Little things like NO CARPET and visible rivets, yay! I've bought an NX-01 too
I will say the exterior of the NX-01 was fantastic. Didn't care so much for some of the interiors though (the bridge and engineering layouts could have been better).
My favorite sci-fi ship of all-time was the Flying-Sub from "Voyage to the Bottom of the Sea." I bought and built that model more than once. That and the "Spindrift" from "Land of the Giants." Just sayin'.
