I always try to buy used as well when it comes to big ticket items like vehicles and tools. In my region though, the ask is too high on good used tubs. For instance, there are 3 used Jacuzzi J series for sale in Craigslist. All have an ask over 3500, are more than 4 years old, and will have void warranty if moved. It will cost me close to 4K to get those tubs in my backyard. Replacement is about 7500. Not enough of a buffer to make buying used worthwhile. Sounds like you did okay though.
