Mercian and Woodrup still building traditional steel, maybe the two most prominent larger-volume mfrs. But you'll be starting at US$1k+ instead of $600ish like BJ.
To be fair they weren't quite that cheap, especially if you were stateside. The prices went up a little bit in the past year, so a totally basic Audax End-to-End or Olympus would still set US buyers back
£700 after shipping, which is about $900 lately. Just a few basic upgrades pushed even the least expensive frames well over the $1,000 mark in the end. Still, Bob Jacksons were definitely the most competitively priced, traditionally made frames around and I will continue to regret not going for one when I had the opportunity.
