Used is the way to go if you are patient. Most of the used ones around here are worn out or of age where parts could be an issue. I scored a nice Brown 472 several years ago but had to travel 165 miles one way to get it. It was in a somewhat remote location and IMHO was the reason it was available on Craigslist. Tractor House, Craigslist, Facebook Marketplace, are all good sources.
When I traded tractors and was looking for a 10 footer a neighbor local farmer had a nice Bush Hog he had taken in on trade. I was ready to pull the trigger on it but after some research and valuable advise from RickB, I learned that the cross shaft shock bushings on those can be problematic. I took the covers off both sides and discovered that the left side had a bolt driven through the bushing. Those new cross shafts are very expensive. I know this local farmer and he's an honest guy. He had took the unit in on a trade and run it a little but didn't take those covers off. I didn't make an offer on it. I opted out for a new Titan 10 footer.
I would look for anything used if you have time for anything in a Woods, Rhino, Bush Hog, etc...even a new Titan if you have a dealer close by. A good unit will be pricey but you get what you pay for. Good luck and keep us posted.
