I'm not sure about the size/thickness of material needing to be cut, but another option to consider is a wet tile saw.? The blades usually are diamond.? You can buy diamond tile saw blades for $14 on up depending on the vendor and diameter, if you want to roll your own.....but a new SKIL tile saw only will cost you a bit over $100 (Amazon price) and it comes with a 7" saw blade.
