Was thinking the same LOL you beat me to it. $4000 for a Sunfish is pretty hefty, we don't have a lot of those around. Mostly Lasers, Stars, Rhodes 19, 410, InterClub and the kids learn on N10 turnabouts. All expensive.
I will never forget my first experience sailing a cat....sold my last monohull the next week.
I'll also never forget the first time I pitchpoled a cat....neither will my South African friend who flew home the next day bruised, battered, welted, bleeding and without his glasses.
