$400/ window on average for vinyl is kind of what I was thinking.

When I priced out Anderson 10 years ago at HD - all but one or two of my 16 windows were builder size - just the windows (although interior wood finished) were $8,500 plus tax not incl installation as I planned on doing it myself. Life happened, it got postponed indefinitely, but I really really need to do something about them.

We have to cut away the siding to expose the nailer fin (I did on my patio door) and trim the outside so there may possibly be a bit more labor. My other issue is the current drywall wrap. I wanted to trim them, but I guess interior wrap is the thing once again since this shack was built in the 80's.

I just wish my bright brass hardware would come back in vogue...
