I know this is probably not the right place for this thread, but it seemed pretty 'General' to me. I have a fuel pressure gauge (100 psi) Glow Shift White Elite 10 color. It has never been used. I actually bought it, checked to make sure everything was in the box, and eventually decided to get the edge setup for the insight (to keep it all in one place). I didn't even peel the plastic off the face of the gauge, though I was tempted to.
As I'm typing this out, I have verified that everything is in the box as it should be. From going over my credit card statement (which reminded me of this purchase in the first place), it appears I spent just south of $93 for this gauge kit. I'm definitely not expecting to get that much back, but it would be nice to recover some or most of that.
For those interested, just shoot me a message with what you're willing to pay. Don't worry about shipping, I'll cover that as long as you're not wanting it within a day or two.
