A little while ago I was burgled and lost all my camera kit, so I'm in the process of replacing everything, I'm trying to avoid buying the same stuff again and to buy better this time around and skip the stuff I never used 
Everything I buy will be Nikon, on the off chance my stuff is found.
I've figured this time I'm going to grab an FX camera (looking at the D3 when the prices start going down), and I'm a bit stumped on what wide lens to go for. I love the effect you get from really wide lenses and used to pair my D300 with a Tokina 11-16, however on FX this lens effectively becomes a prime seeing as I'd have to use at 16mm, not to mention the fact using filters vignettes badly on full frame (or so I've read). I took a look at the 14-24 however without modding filters aren't available and if I'm spending that much I want to be able to use what I want with it.
I've been looking at primes, however the widest prime that it's reasonable to expect to find is the 18mm (the 13mm, while awesome, isn't going to happen), and this is expensive and might not have the wide effect I'm after (I haven't seen any examples to say otherwise).
Then there's the Nikon 16-35, wide, uses filters (and 77mm too, the thread of all my other lenses), however is only f4 (I'm aware that wide doesn't need to be fast, but there are occasions where it helps... however VR would balance it out)?
So here I am, stumped what to do for the best.
