The UK has a really good second hand market, London especially, between ebay/facebook/gumtree for frames and bikes. There are literally tons of dolan frames floating about (DF4, pre cursa, TC1, forza). Examples? Dolan Forza with corima wheels (small, full bike) £875. Dolan TC1 (54cm, full bike) £500. Dolan Pre Cursa (52cm, full bike) £300 Dolan DF4 (55cm, full bike) £1125. These examples are just the highlights I picked out after searching for "Dolan DF4" on facebook marketplace.
