I own a 99 ProGator 170DV that I bought brand new. I have no complaints with the boat other than storage space, but then again it is only a 17 footer! As far as handling, I feel that it handles rough water better than any other small bass boat I have ridden in.
To be honest, the only problem I see with a ProGator is resale value...with them not being a BIG name, they don't hold their value like the more popular names. If you are planning to keep it for a great length of time as I have mine, that should not be an issue though!
