Market: music industry veterans that won the race and have boutique record labels for small runs of obscure or promotional or small bands. Have five records printed for the merch table and the next show. Once you have the machine hopefully the marginal cost of a record would make sense for extremely small runs.

Where a band with no money might struggle to afford a $1000 minimum run somewhere else, they might be able to make beer money at a show with records made on one of these. Probably not "economical" in the machine may never pay for itself, but somebody rich buying one as a mechanism to promote musicians on a small scale probably makes sense to them.
