[QUOTE=Mongo]If you're interested in quality, skip the zooms. Zoom lenses from the '70s and '80s were notoriosly bad, and unlike a fine wine, time hasn't made them better.
I have to disagree with you on this one. There are some zooms from the mid 70's and on, that are very good. Check out the older Vivitar Series 1 and Kiron zooms. They hold their own against the quality zooms of today. I've used them professionally for 25+ years now, and they deliver the goods. However, there were, and still are some third party zooms that I would never use.
