I'm told the SZD-54 manufacturer isn't bothered with a US STC because they are selling enough in Europe. There is an STC in Canada. I was also told German clubs are replacing their high time K-21's with SZD-54's.

Looks nice. About 4 points lower LD than DG1000 in both wingspans, but if it's significantly cheaper...

At the time we got our DG1000s it was I believe 60k for ASK21 and 70K for DG1000 (Euros). The difference in performance with all else being essentially equal made the 10k seem obviously worth it.
