Well i went and did it. I bought THE BIG CLINKER!
To be honest touch wood its great. Today i've been tiling the floor in a bathroom i've been doing. The where percelain, about 5mm thick and the Clincker went trough them like butter. When i ran the blade down the first
tile i help my breath a little as i was about to snap and when i heard a faint clunk i was expecting to remove the
tile and see a hairling crack running away from the score line but the cut was as clean and smooth as my butt on the day i was born. After that things got better, i found the hight adjusting lever and worked out how much pressure to applie and all in all for 80 notes i'm well impressed. The only down side is that it is very similar to a Montolit where you have to physically get down to eye level to line up the blade with your pencil mark, but on the plus side's it has the Montolit breaking arm right behind the blade so the you can snap the
tile anywhere along the cut, great for mosaic as you know. And you where right about the ball bearins "Sooooo Smoooooooooooooth"
