300mm tile cutter in a specials bin along the tile section aisle. When purchasing mine earlier today there was about 10 left.
One of the customer service staff demonstrated 4 cuts on a 150mm x 150mm x 5mm ceramic tile and the cutter worked fine. He did say however, if cutting stone type tiles or thicker tiles you'd need to purchase a trade type model costing $300 - $400.
(Note tried to upload a photo however timed out on my 3G service. Unfortunately a generic link to the Masters website.)
Edit: thanks to 'nickxau' I've updated URL to the model of the tile cutter
Is it this one but for $10?
