If you're starting from scratch and not using left overs from other jobs, I prefer VCT (Vinyl Composite Tile--the stuff on the floor in grocery stores and schools). I've put down quite a bit of it, and it is bombproof. It usually runs around $.60 a tile but you can buy solid colors (I've used b and w in checkerboard patterns a lot) but the custom solid colors run around $1 a tile. It is also pretty easy to cut and install although you do have to put down glue and wait for it to dry.
