First question is are you sure you want an open class bird? Do you have someplace to leave it rigged? If you can't leave it rigged I would think long and hard about buying one.

A Std Cirrus or Std Jantar will fly nearly as far on a given day, land in smaller fields, and your friends will help you rig. Early 15m gliders are even better but a little more expensive.

If your heart is not set on an open glider and you are just looking because of price, don't buy one. There is a reason why the early open ships can be bought cheaply. They don't fly much because the owners get tired of rigging them, can't fly cross country the way they want because they are afraid to land out, and have to be home early to make sure there will be plenty of help to derig.

Buy the best trailer you can afford with a glider in it.
