Planet Bike makes a nice rack for $25. It's light, my wife has one on her strada.
Blackburn makes good, rugged, heavy racks. Most seem to get Blackburn. There are a number of superb (usuallly pretty heavy) racks. Jannd comes to mind. Does Nitto still make a rack? There are several small comapnies making superb racks. Saw a link to one here yesterday. I liked it because it works well with short chainstays. I have a very light, expensive German rack whose name escapes me at the moment. It weighs about half what some racks weigh. Funny, I bought a ton of expensive, liightweight gear, and wound up with a bike that weighed a ton....
