I doubt you would wear it out in a month with everyday use. I have a friend
who bought a 10" Ryobi CMS years ago, and built his (two story) house (every
2x6 stud had to be cut), a three car garage and two other two car garages
for other people and a large storage shed. It's still working but the break
is just beginning to wear out.

You didn't even hint at what you expect to do with it, or what your budget
is..

I just bought a 12" Ryobi. Some who used it 8 hours a day would wear it
out
in a month. On the other hand, someone who only wants to cut base molding
would want a 10", and someone needing to cut 1x12s would need a slider.

For me, the Ryobi 12" made sense; it might not for you.
