Just to add to the long list of those saying "Don't be deterred by
daily rigging" - I have an ASW15, my first (and possibly last) glider.
It is simple to rig with one helper with the wings going on in a
mattter three or four minutes. There is some futzing around but very
little. I may get a rigging aid for days when I want to be ready to go
as soon as the tow pilot shows up but haven't felt a pressing need
just yet. I don't know what you're planning on spending but there
plenty of reasonably priced (mid-20s and less) gliders on Wings and
Wheels. Metal is easy to care for but that paint doesn't last forever
and repairs to fiberglas tend to easier than to metal. Good luck with
whatever you choose - just don't get too wrapped up in the "leave it
tied out" school of thought. Rigging glass is not that big of a deal.
