I think this has been stated already, but yeah, some cars still come with them installed.
It isn't a straight trade for worse, I personally prefer my hand-cranked windows ('96 jeep). My car is 15 years old and the windows work as well as the day the car was made. My father has a ford expedition, and the power windows lasted 3 years. Repairing it was expensive, and annoying. He didn't feel comfortable driving to work, because the window wouldn't close. He also had to wait for a week for them to repair it since they had to special order parts. From what I've heard, repairing manual windows is 10 times easier. I can't vouch for that, since they haven't broken yet.
Personally, I wouldn't think it's worth considering it a dealbreaker (if they weren't available), but then again, if you are spending a lot of money, I would say make sure to get what you want. I would rather spend $100 on what I want, than $80 on something that's close to what I want.
