I would advice to get a brand new one like I did 3 months ago. You could check with online store near you. Sometimes, thye would give you discount by offsetting the shipping cost. With equipment like this, you need to have at least a year on manaufacturer's warranty. If you buy an old or used one, you may never know the history of it. JUst adding few more bucks, you could own a new one and a peace of mind. currently, I'm happy with my brand new chiller. No frills or worry.
