Opinions... you know how the saying goes... LOL Remember that a camera is nothing more then a box to hold the film and stick a lens on it... and the lens is what actually "takes" the image and puts it on the film, good or bad depending on a bunch of things, but the most important is to have a lens that does not diminish image quality. The zoom you are using may be versatile, but consider when a fixed focal length lens may be required to get the results you are wanting. If it were me, and the F3 body met my needs and likes, then get another one that's been gone through by KEH, or send the one you have out to KEH.COM for a complete CLA and shutter. Use the rest of the $1500 for a couple of pro lenses. Just my 2 cents.
