L.e.d. kit price?

[86FireBird]

I have this City Glow LED under car kit that i have no intention of using. I want to sell it but i have no clue what its worth, i know similar kits go for anywhere between 200 to 250 bucks.

If anyone here has bought this or knows what its worth I would appreciate the info.

Thanks
