Dont forget the running costs. Insurance is usually related to hull value.
If you go glass remember not all gell coats last the same. In our club we
have several Discus's where the gell coat needed replacing after about
15yrs. However out Grob 102 mkIIIs are still fine after about 30yrs.
Other gliders in your bracket include DG100/200, ASw19, std cirrus,
Mosquito. Dont like the corrosion problems with aluminum glider. They are
usually hidden.
