Nikon Coolscan V advice sought

[f16sunshine]

I know this seems like a well beaten horse but, I hope to get some help here.
Could anyone give me some refreshed feedback on this scanner.
I use an epson V700 for all my scanning now and would like to get a dedicated 35mm scanner.
A friend on another forum has a Coolscan V freshly back from service at a nice price.
My concern is primarily what driver to use? I run the latest OSX Lion.
Could anyone running Lion and Coolscan V please report?
Also, for scanning that will include 90% B+W Negatives... is the CS V a worthwhile improvement over the V700?
I don't do a lot of 35mm. I would like to see some improvement over the quality I'm getting when I do shoot with 135. Is there another scanner I should be looking to?


Thanks in advance for replies.
