Keep in mind that the 10-17 is always fisheye, though less at 17mm. I like it and would never sell mine. Note that 17mm on the fisheye is like 13mm on the 12-24, so there really is not a lot of overlap with those two.
The 12-24 is a very useful range, and goes very wide but with straight lines, and has excellent image quality.
Sigma 17-50 is an excellent lens, but it has a bit of overlap with the 12-24. I would suggest the Tamron 28-75 instead.
The 60-250 is somewhat large. Unless you want the faster lens, I would suggest the smaller 55-300 that has very good image quality, for a lot fewer dollars.
So, whatever order you want:
10-17
12-24
28-75 this also focuses pretty close.
55-300
