Mavic, Sun, Velocity, Weinmann. DT Swiss spokes 14 gauge and some Formula hubs. 36H in 3 cross pattern.
I've had good results from spinlitecycling.com, harriscyclery.net and two local bike shops. That deal from velomine on the the Sun M13 with Formula hubs is not a bad deal. For extra shiny rims, try the Sun CR18.
