jjj, there are some on eBay now, so you might want to look there. Shipping by JapanPost is not too expensive...
In VueScan I make a flat, washed out looking scan, which ensures that I have all the detail in the shadows, and then edit in Photoshop. I've made very good prints upto about 13x20, from a 120 negative. I've used only Fuji Reala for a very long time - no transparency film at all. The preset film curves in VueScan actually are quite good. I tried a demo of Silverfast long ago, but didn't quite get the hang of it.
