Yes, I do and everything I have is Nikon except that one battery and a Sigma lens.
Interestingly, I subscribe to NPhoto, the dedicated Nikon user magazine and they regularly recommend 3rd Party accessories, e.g. D7000 Hahnel grips and the extra power batteries, GPS, remote triggers and a host of other non OEM products! I actually find that quite strange and am surprised Nikon haven't commented, but in fairness all photo mags do too.
Masses of Nikon users don't seem to mind connecting a third party lens to Nikon cameras and that's got electrical connections and electronic components!
I'm sure this whole issue deserves a forum post on it's own.
