Thanks for the tip Kurt. I should be OK, bought it from my local reputable retailer.
Jon, I really appreciate the info, was not aware of the UHS-1 standard nor that the D7000 was compliant with it . That sounds more suitable for me, I can be a bit of a masher when I get on a good bird at close distance. 60Mbps ought to empty that buffer at a decent clip. I'll go with what I've got for now and pick one up this winter when they hit the market. 32Gig card would be nice too but may have to wait for prices to come down for that.
Next up on my get ready for the D7000 plan is an external microphone. When I looked a long time ago I thought they were cheaper!
