Looking to sell a lamp

[Jagger Robert Brammer]

Hi,

Looking to sell this 16" Rocket Lava Lamp. Anyone know how much it's worth to put on eBay?

These were mid-2000s imports, I forget who sold them. All black, that I've seen, with the liquids often pink/purple or pink/clear. I'd think starting at $40 and seeing where it goes is solid.
