AX2000 when for similar money there are plenty of good Rans S6,s out there
Not so. A decent AX2000 with a 582 engine should be gettable for £5k. A Rans with a 582 for that money would need alot of work.
Hence the advice to get an inspector to look at it first - the quality of a second hand microlight (I mean the standard to which it has been maintained) can vary a lot, and this might not be obvioous to the untrained eye.
