There's a rather nice Aerotec for sale on this forum. Not sure if it fits your budget, but does look rather smart. Not cheap by any means although they do hold their price, and are amazing bits of kit!
Bombard Aerotec 380
There is also a rather smart Tohatsu 9.8 two stroke on here as well.
Tohatsu 9.8 2 Stroke, only 20 hours use!
Not strictly 'cosha' however to buy (or sell) a post 2006 two stroke for private use but still a nice motor. Although worth noting the Aerotec will take up to a 25hp for serious fun!
No connection with above adverts by the way. 😀
