Genghis - have you tried the Yak52? Eats Harvards for brekkers at a fraction the costs. But even at twice the running cost of the dHC1 together with inifnately more power and better aerobatic capability than the Chippy, I'll take the old Brit classic over the '52 any day (and I had a share in a '52 for a few years so do know them quite well).
