I'd love to have the space for terrain tiles, but honestly they're a non-starter. I don't have a huge amount of storage space and do very little gaming at home, so transport is an issue as well.
The cloth I used for that last game is game club property, and I'm not a fan of the old-school billiard-table-green look either.
The cloth in this photo is also a loaner, but looks one heck of a lot better than the older one:

This was Sunday afternoon's RCW outing, in which the Whites punted the Reds, who were trying to hold the edge of the town with a couple of rifle sections and a Maxim HMG.
The mat here is one of Hotz Artwork's "European field" mats, a much greyer green with some stenciled/sprayed patterns in different colours. I'm either going to buy one of these, or do something similar up myself if I can find suitable fabric.
