Thoughts on Fixed Gear Cranksets?

I am guessing you would welcome a break from Interbike at this point, so I am going to take advantage of that by asking for advice. Just in time for the cold season, I finally have a dedicated fixed gear frame to replace my Moser conversion. I will tell you about the new frame later, as it's part of a larger story. But suffice to say I have it and it's nice. My plan was to simply move all the parts from the Moser onto this frame. The parts are rather plain and cheap-ish, but they will do for now and maybe in a year I will upgrade to something fabulous and Phil Woodsy. But the one thing I forgot is that the crankset I have on the Moser (Sugino RD2) has the wrong length cranks for the new frame. The Moser had a low bottom bracket, so the cranks I have on it are 165mm, but the new frame has a high bottom bracket and I want to use 170mm. So I need a new one and therein lies my dilemma: I am clueless about single speed cranksets.

For example, one option would be to just buy another inexpensive Sugino RD2. However, I am told that this is ultimately an iffy idea for a fixed gear roadbike, because it's not made for a track chain. Also, if I do plan to upgrade the components, it doesn't make sense to buy cranksets twice - maybe I should get the nicer version already.

And the "nicer version" is apparently the Sugino 75. It is a Keirin-approved track crankset and is extremely expensive. Why I need it, I couldn't tell you - since my fixed gear frame is not a track frame and I won't be racing on it. Even in terms of aesthetics I don't find it all that spectacular. A friend might have one to sell secondhand, in which case it may be worth it - but otherwise I don't get the appeal of the Sugino 75 for non-racers.

There are also the American made cranksets, such as this one by White Industries. Expensive, but less so than the Sugino 75. And while beautiful in its own right, I can't decide whether it will look right on my frame - the design seems a bit busy.

The Paul's "circles" crankset is simpler, but part of me thinks it should go on a bike with Paul's  drop-outs, which mine does not have. Is that silly?

It is also worth noting that the "nice" cranksets call for equally "nice" bottom brackets, so the real price differential between these options and the Sugino RD2 set-up is even greater than it seems initially.

Of course my ideal scenario would be not to go with any of these, but to find a beautiful vintage Campagnolo Pista crankset - for a miraculously low price, of course, and with just the right length cranks. No such luck though, after months of looking.

So, dear readers: Any thoughts? What is your preferred crankset for a fixed gear roadbike and why? My frame is lugged and fairly lightweight and I'd like the crankset to look classic. The bike is not for the track, so all the debates about tiny differences in stiffness are not really relevant. Beyond that, I have no idea. Help?
