I'm having trouble understanding the rules with respect to maintaining an E-LSA or EAB Zodiac 601HD. I originally wanted to build this aircraft but it was for the wrong reasons. I'm no builder. No time, less patience than needed. I spoke to a gentleman who told me he once built an RV6 for $35k more than he purchased one for later. I just want to own the equivalent of an S-LSA for a fraction of the price, if that's even possible. So, if an aircraft is built by someone else, is there any way I can be certified to maintain it and annual it? If I have to build 51% of it, I will, but again, I'm not interested in building.

This is confusing and with it currently being a buyer's market, I'd like to know exactly what I'm in for as far as ownership costs and the like. Forgive me if this question has been asked a thousand times. As a matter of fact, I would settle for a link to a comprehensive explanation to this E-LSA/EAB/S-LSA "who's on first" quandry.

Educate me, please.
