Good alternative to a proper CF card?

I bought the CF card adapter in order not to have to use the expensive CF cards, but also good but cheaper SDHC cards.
Everything works beautifully and just like with a real CF card. The continuous shooting my Canon 7D is stored as fast as elsewhere and Full HD video to be stored without any problems.
Since last week, however, the CF card is folded back unfortunately 3 pins in my camera when inserting slot. Consequence is that the card can not be used properly, and thus the camera can capture any more images. Now the camera for about 200 must be replaced for repair to the CF card slot. The card is also the Canon Service and will be checked whether it has caused any damage to this.

After clarification, I will adjust my review again.
To date, I was certainly very happy and just hope that the cause is found and the adapter was not to blame. Otherwise I would rather buy a real CF card of a well known manufacturer, since I've been saving this time at the wrong end.
