Aston hit the nail on the head , the sigmas are great but i prefer my montolit mp 75 to a similar or bigger siggy , i love my siggy that cuts up to 530 but prefer the monty on larger tiles, how do i know? was working with my bro in law on a big job , 600x300 porcs he had his sigma 93 set up and i had my monty ,tried the sigma at various times nothing wrong cut well but i felt the monty was the better cutter to use..
