I ran 3 dedicated 20-amp circuits about 25' in length. With the cost of 12 guage conduit, 3 breakers, the outlet boxes, and the installation, but not the Power Ports and other outlets, it was $400.
One thing though. Have the electrician check out the house ground. My ground rod to twisted wire connection was loose. Tightening it positively improved imaging and depth--kinda unbelievable, really. Then, at a later date, I added a second ground rod. This involved installing (a foot underground) an 8'-10' extension of 6 guage twisted wire from the existing ground rod to a new 8' ground rod. The result: More depth of soundstage and more layered depth, where I could tell distances front to back of the musicians. I suppose not everyone would call that an improvement.
Still, the point is the cost was relatively small at about $100, and it yielded, to me, quite an improvement. Not to mention the benefits of safety and a better video picture.
