1990 Sport 20 - What is it worth?

[bigbluebirdy]

I own a 1990 Sport 20, with a 1985 Mercury 150hp Black Max that runs like a champ. I don't think I'll ever be able to bring myself to sell it, I love it so, but I've always wondered - what's it worth?

The Sports' in good condition. The Merc got a new lower unit in 2004, and the powerhead is original.

Just curious if anybody wants to venture a guess?

Thanks.
