Digital Photography has an article on "All-In-One Zoom Lenses". Read it over and over. Glad to know the Sigmas, Tamrons, and Tokinas will work.
My d3200 will probably be new to take advantage of warranty, and add-on warranty. The lenses will probably be second hand. Still planning on the 18-55 "kit" lense for starters, then see what I'm doin' before buying anything else.
I treasure your advice. My county is kind of sparse for camera shops. 35 mi to the nearest, and it's a second hand store. Hard to just drop in and chat. The next is in Orlando. 40 mi.
