Yes, ST/ETT when compared to a square frame.
Not in a rush, so will wait for the right frame, I suspect something is out there. Shipping from Europe on Ebay is reasonable often enough. Im aware of the Soma, but would definetely prefer vintage and lugged. I'm more concerned with something in the correct size and interesting lugwork over steel quality in the end.
Building it myself would be nice. Im in the process of finishing up acquiring everything i need for brazing (torch, bottles,etc.), hoping to start building some personal frames this winter. Would still be awhile before I'd think about doing it for the public in any form, but will be nice to try some stuff out!
