I know the 80mm is expensive, but it's in the same order of pricing as the Nikon 105. It's also the best 1:1 lens I have ever used. I have used the Minolta and Sony ones extensively and the Nikon.
The stabilization is superb and makes a real difference. In addition, coupled with the 1.4x extender, you have a 180mm reach in FF terms, which gives you lots and lots of working room.
Finally, unlike other macro lenses, it's no slouch in terms of focusing speed in non-macro circumstances, which makes it a pretty decent telephoto lens.
Finally, it's by far the sharpest macro I have ever used, and it's probably the sharpest Fuji lens out there. I sold my 90mm F/2 after I got the macro.
I'll post some samples in this thread.
