Hey guys/gals. Looking for a little more information here.

I am looking into picking up a good steel frame for general riding around town and going out on photo runs (semi-pro photographer, need to be able to get to shoots and such).
I know about the Kilo and some other "entry level" bikes. I am looking for something, that's higher on the quality scale.

Ideally I'm looking for a good quality frame, steel, that's going to last me for a while that is on par with some of my other components (good quality, reliable). What I need help with is figuring out what frames are one step up from the "entry level" arena.

I've researched this a bit but would appreciate some input from all the experts in this area, thanks! ^^
