High quality parametric EQ units are by nature fairly expensive and more than a little complex in their operation. At MSRP the top flight units (Manley, Focusrite, GML, Drawmer, Avalon, EAR) are in the $3-4k, or higher range. Check out digibid.com for used items on auction. Although it's not a parametric, check out the Night Technologies EQ3-D. It lists for slightly over $1k and has very flexible low frequency shaping capabilities.
