I bought a V3I about four years ago but was hooked on my DFX with bigfoot coil and hardly ever used it. I sold my DFX and bought an Equinox 800 due to the fact my shoulders are shot and I needed something light weight. What are the values for resale with wireless headphones for the V3I that have little use. I don't want to ask to much and not sell it but not give it away. Thanks for your help.
