Some day soon Octalinks will be very hard to find ($), the first version is getting that way now, fortunately you are looking for V2.
I have a watch set on eBay to email me whenever a v1 109.5 is posted for under $20, I get notifications literally almost every day.
I have a nice old Tom Ritchey crankset that a friend gave me, along with a BB that is too long (115 I think), puts my chainline out too far by 2 or 3 cogs. Someday when I care, I'll snatch up a 109.5 and put it on my commuter.
