I know that TSA towed with them for years, but due to maintenance
costs, went to Pawnees. I believe it was a good move.

GBSC (http://soargbsc.com)has one L19 and 2 Pawnees. The Pawnees cost
roughly 50% less to operate than the L19. We keep the L19 to train other
tow pilots, something difficult to do in the single seat Pawnees.
