Used this
http://www.harborfreight.com/1-1-2-half-hp-bridge-tile-saw-with-stand-97360.html. to lay 2200 sqaure feet ( kitchen, 2 bathrooms, walk in shower and hall way ) of tile in our new home. Get a good blade. Tile size was 20"x 20" tiles and was very accurate until the very end when the roller bearings rusted ( took 2 months to lay the tile ) and the saw would not roll smoothly. Bought the extended warranty and took it back and got a new one.
The water gets all over. So set it up outside/ in basement. I've used some porfessional saws which are really nice....water does'nt get all over but with a $2500.00 price tag I can clean up a little water mess.
The saw blade stopping problem described by Ksullivan is something I ran into also. The blade has index and can slip. Just make sure the index lines up with the washer retainer and the blade . Tighten and she won't slip.
