Which one do you want? And how much do you want to spend? You can find Nikon 60mm 2.8d Micros all day in pristine and/or refurb'd condition on eBay for $225...
Or a new Tokina 100mm 2.8 macro for $379...
Both are full frame lenses and excellent lenses just the way they are... The macro is icing on the cake...
