Just thought I'd share, because it took me many years to find a blade I'm happy with. I have been using the MK Hotdog blades for the last couple of years and am extremely happy with the performance. I am a full time tile setter and one 10" blade lasts me about 8 to 10 months, installing mostly porcelain and stone. The MK blades stay sharp until they are right worn out. Also the wear is very even and at the end of the blade life there is only a very thin bit of diamond left.

There are certainly other blades out there that perform that well, but they all cost about 30 to 40 % more.

The Hotdog is what came on my saw years ago. I couldn't get enough life out of because it's so thin. It made for good cutting at first, but warped terribly after a while. Maybe I abused it too much.

I don't know when I'll be getting another one, but I hear that the Raimondi T3 Razor is very good. Think I'll try that one next. http://www.tiletools.com/product/10-t3-diamond-blade-raimondi-razor-t3-triple-threat-560.cfm
