Cheap windows look great for a few years, then the problems arise. And it's difficult to find durability reviews on the internet.

I put 14 windows in about 5 years ago, 3 more about 3 years ago. So far they have been completely trouble free and look brand new.

They aren't cheap, but neither are they expensive. If one is concerned about value, rather than cost.i consider these to be a top choice.
