new lens debate

[MasonDuo]

So I currently have a D3100 with
Nikon 18-55 "kit lens"
Nikon 55-200 4-5.6 VR
Nikon 35 1.8g

I've been saving up a bit to buy another lens, and with that there is always a debate on wants and needs. So I really would like to get a wide lens. The one i was looking at is the new Tokina 11-16 (eta was May, now pushed back to June-Aug). So I've been debating on getting the Sigma 10-20 4-5.6 , but I would hate to drop $450-$500 on a lens that I might get rid of in a year or two. So does any here have the 10-20 sigma, is it worth it or should i just wait for the tokina. IF I don't go with the 10-20, I was then thinking about putting the funds towards a different lens and then get the new tokina 11-16 early next year. Those lens were the Nikon 50MM 1.4g or 1.8g or the sigma 50mm 1.4

Sorry for the long post, I've been going back in forth about this for the past 2 months, and now in less than 2 weeks I'm off to WDW. And i still have not decided on anything:brick:

I've got the Sigma 10-20 and its been a really good lens. All my kit for my D300 is Sigma and its produced the goods every time. The only Nikon lens I have is the 50mm 1.8 and it is a great lens, just depending on what your using it for, with a crop sensor, it may be too close to the subject than you would ideally like.

17-50 2.8
18-200 3.5-6.3
70-200 2.8 *
150-500 5-6.3 'Bigma' *
*Also got the 2.0x adaptor for use with those two

Side by side they may produce similar images... but the Tokina is better built and faster at 2.8. Unsure how much you may need the 2.8 but having that constant aperture is nice. I use it often... although it has some nasty barrell distortion.
