Newb question.. I was reading an article today that mentioned the need of a strong lockring, good hub yadda yadda for riding fixed... I'm pricing up wheelsets and am thinking Ksyrium Equipes right now, but have noticed them with the likes of Ultegra/Dura-Ace/Mavic hubs and wondered whether these are still considered good/hefty for fixed use. I plan on riding my FG around town, and as we all know the streets here are ****, so I want to make sure I have some decent circles guiding my way.

Are there any fixed-specific/preferred brands/things to look for in both hubs and rims/wheelsets? Local stores/tips Keith, I respect your reputation amongst the crowd here and I want the best for what I can afford (I think I'd go as north as $350/4 - but I need other stuff for the build too, so can't budget more now).
