Bike seats? Comfort, men's health

Mainly upright riding position. Got to be comfy, on hard tyres and allow decent ventilation; it'll be used for rides of an hour, max, so looking at below £50 or $ equiv. (Not much in it these days . . . ) Like something you sit on, and think "Ohhhh! That's comfy . ."
There's a dearth of decent reviews on most stuff I've researched, so . . any bargains out there? :D
