It's probably too late but for what it's worth, I have been using one for two years (Flextight Precicion II) and I continue to be impressed by the scans. I have owned a dedicated Konica-Minolta film scanner (sold) through the Epson (Medium format) and now the Flextigh (alongside Epson V700 with Betterscanning film holders). I use Epson for proofing and Imacon for proper scans and this arrangement has been great for me. While Epson is capable of reasonable scans, when it comes to detail, tonality and colour consistency, there is simply no comparison to the quality of the scans you get with the Flextight. Yes, it has it's quirks (which scanner doesn’t) e.g. you need to use tape to hold film in one place in the magnetic holders but the overall design, quality of the machine and ease of use are great. I use the .fff format from Hasselblad with their latest software on my main Windows 7 64bit machine to process the files. You get a type of a RAW file, scanned at a maximum resolution so you can perform any colour adjustments, sharpening, size etc. as you please.
I got it of of Ebay for £1800 in the UK (mint condition with a scanning station - an older Mac with SCSI connection used only for scanning) and thought it was a really good deal. Especially that it was ready to use out of the box. Never had any issues but there are some scanning tricks and methods you need to learn, as with any other scanner, to get best results.
Basic preventive service in the UK costs about £250 + VAT but you pay £150 for shipping (Including Europe, shipped in a purpose built case) a friend from Gemany had one successfully serviced recently (belts, springs, lube + adjustment done). I have also used Hasselblad UK before and they've always delivered good service.
Saying that you can get basic parts like tensioning springs and belts, the lube etc. for peanuts compared to Hasselblad prices if that's the ONLY thing you require. Changing these parts is very easy. It also eliminates the need for shipping it anywhere. You should visit yahoo groups and search for Imacon discussion group, really helpful bunch of people and a great database for any issues people may have encountered with these scanners, including compatibility information with current OSs.
All in all, I would still recommend one.
