Best fast and wide (budget) prime?

Hello,

I'm considering to complement my EF-S 10-22 f/3.5-4.5 with something faster and maybe not so wide. I'm looking at the 24-35mm focal range.
I intent to use it at its widest aperture, so it should be usable wide open
My budget is set about $550 and I'm looking at some 3rd party lenses.

For now this is in my list:
- Sigma 20/1.8 - not getting very good reviews, seems like f/1.8 is not so usable. Pros - auto focus and price ($460 second hand)
- Samyang 24/1.4 - mixed reviews, seems to have pretty strong vignetting and low resolution wide open. Price is $630 new which is a downside, too.
- Samyang 35/1.4 - seems not a bad choice, but only manual focus. Well I can still use LV to focus for astronomy, but it will be not so useful in everyday shooting. Price here is about $530 new (no second hand copies at the local market).
- Canon 50/1.4 - it is a bit out of my focal length, but it is fast, has auto focus and it is cheap ($370 second hand), so that's why I'm considering it
- Canon 50/1.8 - even cheaper, but I had that one before and it was the reason I don't like 50mm on a crop
- Canon 28/1.8 - good reviews, price $700 (suggested by chris_holtmeier)

For now the winner seems to be Samyang 35/1.4. What do you think? The scariest thing there it Is the manual focus. Lots of people are telling me "Oh, man, once you start shooting with a MF lens you won't wish for anything else" but I know people are different. Is MF scary for you?

How about Sigma 30mm f1.4?

It seems there are two "Sigma 30/1.4" lenses.
One is EX DC HSM which is getting mixed reviews over the web. I can't find it anywhere on the local market.
And there is that DC HSM/A (Art) lens which is available only new for about $640. I can't find any reviews about it.

I really like my Canon 28/1.8. Bought and sold a 35L, kept the 28.

If you are willing to consider entering the world of manual focus start looking at older adaptable MF lenses. There are some great fast wide primes out there and you can buy a box full of them for the $530 price of the Samyang.

Nothing scary about it - not that long ago MF was your only option.

It is not exactly like that at my country. Second hand market is small. There are couple of lenses like 17-85 and kit lenses that you can find easy, but other models are scarce. New gear market is small (1, maybe 2 serious photography equipment shops at all). Incomes are not so good and prices are a bit too high.
I see there are international online sellers, but most of them are not willing to send lenses to foreign country.

Canon 28/1.8 is about $700 new. A little on the edge, but going into my list.
