Once I got my first 4 stroke, there was no looking back. I have Saitos, Magnums and OS, and like them all. The Magnum for the price and good mileage, the Saitos because of the looks and sound and the OS because it's an OS! IMO, the OS's are probably the best but I prefer the Saito's even though they slobber like a pig. They just remind me of an old Harley. They leak oil, but they are just so cool!
