Barely used as I couldn't get it to stay on my de-rimmed 20L. Only for folks with a rimmed tank.
As it is the deluxe version, it comes with the lid and Tom's aqualifter pump. I will also include 2' of black airline tubing if requested.
Asking $70 ($100 new).
Would prefer to just sell it in person but payment via PayPal is fine too. I'm willing to drive up to an hour to meet up (I'm in Fayetteville). Send me a PM if you're interested.
