We have a 25 year old house and the windows leave much to be
desired. They let some cold air in and are a pain to work on (need to
pull out little pins to slide them, a real PITA.

So we have started looking at replacing them with something
better. Any suggestions? We are*looking mostly for crank operated
ones.

Has anyone did any windows replacements recently?

I would hire a contractor, but wanted to get a feel of what is good
and bad, first.
