I've got an analog (old version, 1 year old) 1/15 mini arctica for sale. Comes with plumbing kit. $200obro. Cost me $350 brand new+plumbing kit. The new digital is $400+shipping online, even more in the store. This chiller works well, but I no longer need it as none of my tanks get hot at my new place. Can be plumbed inline on nano returns or ran off a MJ1200 or similar pump. Rated to chill a 50gallon tank by 10F. This unit works well!
