If'n you have a lot of tile to cut you might want to consider renting an electric, water-cooled tile cutter. We rented one when we tiled the kitchen back-splash and it was faster, cleaner, and more cost-effective ('cause we ruined less tile). Just something to think about. LSA
We only have a few pieces, maybe two dozen at most, to cut, so we figured a cheapo tile saw that was usable on our timetable rather than a rental, would be the way to go. If we do a bigger project though, yeah, we'll prtobably rent.
