Frame upgrade

why do people only think of bob jackson and mercian when looking for a new frame
there are hundreds of frame builders out there ( some cheap some expensive admittedly maybe bobby j's are the only ones who do frames at a decent price )
go through fixedgeargallery.com / velospace and look at the vast array of bikes out there, keep flicking till you see something you like and then go for it

theres almost too much choice TBH. I'd try to narrow it down

Geometry? (track, semi track, road)
Material?
if steel (lugged, TIG, fillet brazed)

If you are transfering from a previous build, this will narrow it down for you.

If I were to buy a new frame this might tempt me
