Thanks for the replies. It is good to know that the IQ is pretty similar for both lenses so now my decision making becomes a bit easier.
There is a deal going down locally where a used 200 prime in excellent condition is available for about $ 500 - $ 600. I think I'll get that and it'll be useful when I need to carry less weight on my hiking / biking trips.
I'll see if I need the zoom once I use this lens. I don't think I could lose too much money if I were to sell it again
Cheers ... J.R.

I come here to learn something new, not to learn how bad my gear is - I know that already ;-)!
