Wide angle from 17mm

[skankmaster]

My new years resolution of getting only one lense a year begins..
Looking for a wide angle lens and a number of choices have appeared that have caught my eye:

(i) Canon 17-40L f4
(ii) Sigma AF 17-70 f2.8-4.5
(iii) Tamron SP AF17-50mm f2.8 XR Di II LD
(iv) Canon EF-S 17-55 f2.8 IS

Now Im not planning to get one until late summer, so have plenty of time to absorb opinions and read reviews - option (iv) is an unknown quantity at the moment and would be the most expensive of the lot. Im only planning to get one lense a year - honestly Mr/Ms bank manager!

your opinions and experiences welcome.

I went into a camera shop yesterday to look at what was available - the sales guy mentioned the canon EF-S 10-22 f3.5/4.5 and did a nice sales pitch on it - I dont know anything about the lense so didnt buy it. However, I have noticed the price is almost the same as for the canon 17-40L - in exploring my options for a wide angle, would you say the EF-S10-22 would be on par with the 17-40L for quality? or is it just that you pay a premium for a wider angle lense?

whoops - from 17mm to 10mm, what was i thinking of

I already have the range 28-75 covered. It sounds as though I only need a lens from 17mm onwards. A 17-40L looks like it may be useful. It'll probably be the only canon L i'll own.
