Well here's my guide
SHOPPING
Flat tiles
Star Wars Galaxy Tiles – Printed, heavy duty cardboard. Double sided to allow for multiple appearances. 4 sets are enough to cover a 4’x6’ table. Also compatible with their Dungeon Tiles sets. Probably the best value for the money. The only disadvantage is lack of doors.

Space Hulk Tiles – If you have these already you’re good to go. If not they can be downloaded here but you’ll need to print and mount them yourself:

DOOM and other boardgames – Not much to say, if you have an appropriate game like Fantasy Flight’s DOOM you’re good to go.

Litko Aerosystems – Unpainted plywood tiles and doors that interlock. These require painting but are good quality and fairly cheap. I use their doors. But I had problems with warping when I assembled them.

Three Dimensional corridors
Dwarven Forge – The gold standard of dungeon terrain. Pre-painted, tough ceramics with a choice of medieval and science fiction sets. Expensive but worth the money.

Hirst Arts Molds – Hirst Arts sells plaster molds for casting your own blocks and details. They have several science fiction sets that would let you build anything you want. The most labor-intensive option but potentially the most rewarding.

Ainsty – Old Crow sells Ainsty’s line of space ship interiors. They’re resin, not cheap, unpainted and have to be shipped from the
UK. But they do look great.

IMEX models – IMEX makes gothic buildings, chemical plants, electrical plants and other terrain kits. Their kits are modular and fit together well and could be used to build corridor walls.

Games Workshop and Forge World terrain – One of the easiest options for building your own. Cities of Death walls and Forge World terrain can be used with plasticard, wood or foamcore to create detailed ship interiors. It won’t be cheap but it will be rewarding.

Make your own! – Mad props to anyone who does. It can be done with wood, plasticard, plumbing supplies and other materials. Here’s a tutorial I found.

Machinery, consoles and other decorations
Scotia Grendel – Although they do not have corridors Scotia Grendel has a line of science fiction terrain pieces that can dress up your ship. As with Ainsty they’re based in the
UK and not cheap.

Copplestone Castings – Copplestone’s Kiss Kiss Bang Bang line has Cold War era consoles and doors meant for mad scientists underground lairs but useful for us as well.

Armorcast – Like Scotia Grendel they have lots of science fiction bits for use. They’re not cheap either and based in the U.S. so it cheaper to ship there.
