Like that how to choose?
All are equally excellent (much much much better than taking models in Comex).
Anyway, like #1 best (if really really have to choose one).
1. CF/SD card case like the one given out at the D2X launch(this is nice)
2. UV filters (options to upgrade NIKON NC filterS!!!!!)
3. LCD screen cover/protector
4. SD/ CF cards
5. 50mm f1.8 (option to upgrade to f1.4D with top-up)
6. OTG <---something like Digitmate
7. Electronic dry...
