I think $160 for the crankset is a very fair price. As was mentioned previously, the TA' cranks were pretty poorly made (at least the 2 sets that I had) and flexed quite a bit when I would pedal hard. Considering what you would pay for a vintage TA crank and if it needed new rings or you wanted to change the gearing to suit your taste, you could easily pass $160 in cost quickly.

As I had stated in the thread about triples, I am a fan of compact doubles now. I am currently running 46/34 w/ a 10 speed 11-34 cassette and have had no trouble getting my 42 year old butt over the largest hills in my area. If I lived in a more mountainous area the VO crank would be a nice way to lower the gearing further, if needed. Not having a large ring(50th or greater) is not something I miss. I rarely ever feel I need taller gearing. If anything, I more regularly think of lowering my gearing even further as I get tired!

I like to find deals, sell for a profit and reward myself with bikes and bike stuff I like. Price is relative to how much you want it IMHO. I am another who is equally at home on both ends of the C&V pricing spectrum.
