There are a couple of reasons for your (original poster)
getting a used glider such as an LS-4 or a Discus b.
They are easy to fly and they are high enough performance
to challenge you for several years. At 58 you still
have many good years ahead. Further, it is better
to get a used glider than you can bang up for a couple
of years while you perfect your skills, and then you
can go for your dream ship and then you won't subject
it to the same treatment your first one got. These
are the words of an acquaintance who is a racing pilot,
sells new gliders, and has a glider repair shop.
