A mate was offered a go in an S10 a few years ago (he had a lot of money labelled Nikon hanging around his neck so maybe it was thought that he could afford one!)
He was particulalry impressed with the comment - "adjust the air conditioning to suit yourself"
Apparently very nice but as already said, dodgy undercarriage.
The "pop up" engined self launching gliders are (a bit) cheaper - and there were articles in "Sailplane & Gliding" a year or so back by a bloke who went to Eastern Europe & back on about 5 gallons of mogas!
