Did you find the Tammy 28-75 wide enough for your needs? I am thinking of getting this (if my financial situation allows !!!). I am thinking of replacing a couple of my lenses (Pentax 43mm limited and Pentax-M 50mm) with this lens. The only thing concerned is the lack of wide-end of this lens in my K20D (28mm = 42mm which is not really a wide).
I also got a Tamron 17-50 from my friend. But I am less than impressed by its performance (may be my copy is not good). I need to test it more.
My grand plan is to replace the Tammy 17-50, Pentax 43mm and Pentax-M 50mm with Sigma 10-20 and Tammy 28-75 (I am not sure whether it is good plan or not !!!)

The Tammy is plenty wide in most situations for me. By the end of the month, though, I will have a DA12-24 for when I do need something wider.
As for your plan, I do have some ideas.
--If you can handle the gap in focal length between the 20 of the 10-20 and the 28 of the 28-75, then the 10-20 should be fine, if you'd rather not shell out the money for the DA12-24. If not, then I would suggest continuing to save to the 12-24. I don't know if you've seen some of the images from this lens that have been posted lately, but they're amazing.
--If I were you, I would consider hanging on to either the 43 or 50, since both are faster than the 28-75 and would be beneficial for really low light situations.
HTH,
