"t's practically an EX cosmetics wise except for the fact that parts of the back were really sticky(infamous N/F90 sticky back syndrome),"
I bought a Nikon N90 brand new from Adorama back when they first came out, mine also had the coating on the film door start to crumble off. I called Nikon and they sent me a brand new film door for free. I wonder if they still do this?
I have bought quite a bit of stuff from KEH over the years, from BGN to brand new. For me, the BGN grade stuff is a little too rough looking, but step it up to EX and it is starting to look pretty nice, EX+ from them looks virtually mint to my eye.
Back in July I bought an EX+ Nikon F5, and just a few weeks ago a EX Canon EOS-1V.
