Whilst an LAA machine might not be
much cheaper in engineering, parts mostly will as they do not need to be approved, this approval often multiplying the cost by 10! Beagle Pup brake pads, for example, used to cost 10x the Exact same cost as the (IIRC) Jaguar ones without the CAA stamp on, only difference was that stamp - even coming in the same box! Also, you do not get the problem some Robin owners are having ATM of approved parts just not being available for a simple switch - you just find a suitable alternative.
