VFM either means:
1. VFM Audio, a manufacturer of speaker cabinets and bookshelf monitor speakers.
2. VFM, an acronym meaning "Value For Money."
I'm guessing the latter. Without knowing the particulars of your setup (interface/DAC being used, specifics of your room, acoustic treatment, type of source material going through the monitors, tracking duties, mixing duties, mastering duties, active monitors, passive monitors, etc.), I would say the simple solution would be Yamaha NS10's, or KRK Rokit 5's. They're both readily available, pretty cheap, and each come with a comparable, although different, set of compromises.
