The LSA world is up and running and the new SLSA's are pretty nice and relatively straight forward to work on. It may even be the saving grace for GA at the budget end.
Except for the nuiances of the Rotax and Jabiru engines, everything else falls into place and should show up in any shop.
When in doubt, get a hold of an LSRM-A who has done the maintenance work and inspections on the engines- most of us want to help and learn your trade as well. I for one would like to join the A&P ranks in about 18 months.
