Moped Army

I'm just finishing repairing a 2nd indian moped for a friend, and I'm extreamly impressed with it, both with how it's built, and how it rides, and I'm thinking that I would like a 4 stroke for my self some day and was wondering who all made 4 strokes? I've found a few like the honda pc50's I beleave, I'm kind of a honda junky, and wouldn't mind something older if afordable, but I would also love to have even a short list of 4 strokes that were made.
