They're made by a German company, Hughes & Kettner (sometimes known as just "H&K". I own one and, when I gigged regularly, it seems to work very well. I think I paid around $100 for it. Mine uses a 9-volt battery or phantom power (the output is an XLR connector). I believe the latest version (different versions are referred to as "Mark II", Mark "III", etc.) has a totally passive circuit that doesn't require any DC power source. I don't know if this new one sounds any different from mine.
