Recommendations for a family jetski for property on a lake.

Recently purchased a house on a lake and I am looking to get a jetski for the family. The lake is a 17acre spring fed lake in Florida. The lake is fairly deep water is calm but does have a current as it is interconnected to a lake system. We have a dock to tie to and garage space for trailer if that’s better way to store.

Kids range in age from 7 to 21. Would like something everyone can enjoy. Young kids want to sit down, older kids want a stand up. Would like to be able to pull an inflatable around. Not afraid of maintaining and repairing and would like to keep the price down as much as possible but also want to have something reliable. Budget is $5-6k.

Suggestions for first jetski? Any hidden gems I should keep my eye out for on the used market?
