I bought the Muddy Fox for 18€ and the steel was under 100. Parts were all bought used so the whole build was around 500€. The most expensive bit was the facing tool for the long headtube. I had to buy it and build an extension to ream and face the mild steel tube i used. All the shops that sell those pricey cargobikes seem to just whack the headsets in and told me they didn't have the tools...
