Recommendation for windows - mfg & company?

[Jerry N.]

Wondering if anyone in the area has a good recommendation for replacement windows for rentals (A to A/B property).  A couple of the windows are pretty large (100+ yo bldg) and while the finished apartments will be nicer, wood windows aren't even a budget consideration.  At the larger sizes, vinyl would be needing to be replaced in maybe less than 10 years from the research we've done.  

We've seen Jeldwen windows which can be ordered from Menards in $1M+ SFH properties built or rehabbed by developers.

One company had recommended an aluminum window which seemed to be a good option - Crystal series 2000.  

We've also already researched window types, materials, etc.  Looking for an overall economical longer life option for tenant use.

Any insights would be appreciated.

Thanks for taking the time to read the post.
