I have no specific experience with the scanner you mention. However, I do own a Nikon Coolsca 8000ED purchased from a camera store's eBay auction a year ago (demonstrator model, with warranty.) I use it, like you, for 35mm and 120 scanning of all types of film. It has DigitalICE "stuff" remover (I rarely use it as 95% of what i shoot is traditional B&W film). It has been superb with a few caveats:
1. The NikonScan software it comes with has its quirks, and takes some learning to get the most out of it. I still like it better than VueScan. (Everyone seems to sing the praises of VueScan, and I own it, but its user interface and workflow are awkward and needlessly complex for my taste.)
2. For 120 film you should count on buying the anti-newton-ring glass film holder; the junky glassless holders work fine for 35mm but simply won't hold 120 film flat enough to scan sharply.
Haven't priced these lately but i imagine they are out there in great numbers and probably for less than the $1400 I paid, as its newer and faster brother the 9000ED is out there at around $1900-2000.
You can follow my signature link to my online portfolio; any shot there made from film (all but a couple) was scanned with this scanner from MF film mostly. Give you an idea what this scanner can do.
Hope this helps. Nice to have someone to talk to here about film matters. We analog LL'ers are lonelier than the Maytag repairman.
I own a Nikon CoolScan4000 and love it! The Nikon lens and ICE technology is great. My slides from the mid-late 1960's came out very good! I bought from Cameta Camera as a Nikon Demo and it was 50% less than MSRP and I got a warranty.
