Well, I`ve thought the same, I`m actually putting Singularity onto CD for album releases, but the market I`m hitting is very CD friendly, so it shouldn`t be a problem.
However when I investigated getting DB Records on CD it just wasn`t worth it.
Production costs are surprisingly close to vinyl costs, and there is no distribution network bar doing it yourself, which means cheapy crappy self burned stuff, or again, massive outlay.
