I didnt say stay away from ebay...Mark11 did.....ebay is fine...I bought a enclosed single seat thruster off ebay a little while ago..Sold it to a young guy from vic..He didnt have a licence at the time but did all his training in a t300 so he could fly it....(its on utube)..And he just recently sold it on ebay..He loved it but wanted to upgrade to a 2 seater.
