I did buy a set of genuine Nikon replacement batteries for my D80, I use the MD80 power pack on it so I am packing 2 batteries as opposed to a single. I have been pretty well price shocked at the retailers here when I went looking around for them and ordered from a seller in Hong Kong. If you folks haven't looked for filters and other accessories off shore but find the local retail prices to be a bit on the high side you might want to consider this as an option. I have bought B+W filters from sellers over there and was able to cut the cost down to an acceptable level. Delivery time (remember I'm in AK.) is about 10 business days to get something here.
Just thought I'd put that on here for any Nikon DSLR users
Nothing aginst the shops in Anchorage making a living but sometimes if we're talking about an 'I can wait' item this makes good sense.
