I have an '87 TriStar 190 and bought new. It has a good slalom wake but not as good as the 197 and the wakeboard wake without ballast is very recreational. All I do is ski and the wake is great for that. Even though the boat is 19' the interior is smaller because of the integrated swim platform is part of the 19'. It is not a good rough water boat, you just have to take it easy in rough water and not be in a hurry to get anywhere. Just turn 1,540 hours this weekend and have done nothing other than maintenance and carb replacement. It has been a very good boat for me and my family (1 daughter) and it does what I want to do with a boat, which is ski.
