Bought a 1993 Prostar 205 with 400 hours in 2007 for $12,500. From what I know they've ben going for that or more over the past few years. Bomini top, monster tower (which I could do without), Ford Windsor, great condition, etc. It's been a great boat!
Did I mention it's white with pink and teal accents? It's awesomely 90's - ultimate hipster ski boat.
