Thought I would update this thread as I have
finally made a decision - this decision also affects my other thread on a similar subject about which WA prime I should get:

Wow - between these two threads I sure have beat you guys up about my quandary!
Anyway, this thread is kind of a successor to the linked thread - I was originally going to get a WA prime, then with this thread thought about getting a kit zoom so I could try the different focal lengths. But, I was concerned with being disappointed with the IQ of the kit lens, plus if/when I decided on a prime, it would be another lens that I would need to sell.
I don't know why, but on the way home from work it hit me - why not just get a higher end zoom like the DA* 16-50 etc. This would give me a range of example focal lengths to work with, plus it would be a lens that I would certainly keep if/when the time came to get myself a prime. Also, who knows - maybe this fast zoom will satisfy me enough to even forgo a prime for now.
I won't get into the whole debate between the three 2.8 lenses here - I decided on the Sigma 17-50 2.8 EX HSM - this is the newest version without the OS. I think I made a good choice for now in my stage of indecision - I actually feel much better now that I made this decision and really looking forward to working with the new Sigma lens.
Thanks everyone who took the time to help with with their opinions and input - couldn't have made it to this point without it!
