It's grim up north (London)
There aren't many other manufacturers doing a decent range of modern ready to ride steel bikes (in fact I'm not sure there are any).

My LBS, Pearson Cycles in Sutton still do off-the-peg steel (though I think it's almost exclusively for touring frames these days)
Of course, there's Mercian and Bob Jackson which even are more toward the custom-build end, but they do advertise complete bikes.

Which I'm thoroughly enjoying, and which is a part of what's pushing me to look for a faster / nippier road frame
