^^ yeah, answer yourself those questions first, then we can start with recommendations. Hell, I almost bought a Nikon D5100 kit today, the wife was out and stopped by Target, they had the kit for 50% off! $329 with the 18-55 lens! None of my lenses would fully work on it, but hey, I like shooting manual too.
Yeah, that lens is back in its case, partially assembled now. Once I finally got the aperture ring re-indexed and properly set I gave up. Turns out that there are thee aperture scales on the ring, I guess for different makes of cameras. There were also three cams on the ring inside, I could index to any of them, but only one works for Nikon. I may just got buy another one of these lenses for cheap. I really like the color rendition and softness of it, the CA isn't terible (I've had much more expensive lenses with worse) and its a metal body.
On the hunt for a reasonably fast, wide angle lens now. Something from 20-35mm.
