The G104 does not seem to have a good reputation. The flaps were
created with a "hinge" being a flexible top surface, very experimental
and the results were not good. Also the 104 is only good for small
pilots. The 102, especially the later G102 Std III version are great
gliders.

As a new (effectively) glider pilot, buy something well known, with
decent perfromance and an easy to rig trailer, and fly alot !
