I love the Tamron 60. Earlier this year I got the Sigma 105 that I thought would replace it, but I decided the 60mm is worth keeping. Its small and lightweight compared to the 105. I like the extra reach the 105 gives me at mid-distance. At minimum 1:1 distance though there is only a small difference. And for a lot of things, I prefer the lesser reach of the 60mm. There are some shots from both the 105 and the 60 in my nikonites gallery. Probably none of them are shot at minimum distance. I like to back up, stop down, use flash, and crop the final image. It makes for quick handheld auto-focused shots with some compromise of image quality from the very high aperture and cropping.
The Tamron is a DX lens, so keep that in mind if you long range plans. I got mine mine way back and I can't remember if I got a $50 or $100 rebate, but I've always been happy with it. I think it would a great lens on your d3200.
