Get ecoplus 1/10HP it's cheaper, reliable and room for future upgrade. The cost is almost or cheaper than the 1/15HP.
I heard that the JBJ dicontinued their nano/mini chiller, the old version doesn't have a controller.
I just spoke with their sale rep. and JBJ is coming out with a new mini or nano chiller that has a built in temp. controller. This chiller will be avaliable at my shop sometime next week.
