Product review (5 stars): Sure to please!  Consider adding a filter...
I bought my SCN60 Scotsman Nugget Ice Maker two years ago. I also bought the iSpring RCC7AK RO water filter with alkaline remineralizer on Amazon at the same time to filter my tap water supply. I did this for two reasons, one, higher quality water should reduce scale build-up in the ice machine and two, theoretically it should give the highest quality, best tasting ice. That said, I have friends who don't use a filter and they are also very happy with their units. We have good quality city water in my area so I am sure that helps. My unit drains by gravity, so I didn't require the drain pump option. Many people install their ice makers below the counter. We installed ours at counter height and built it in which we really like because we don't have to bend down to get our ice. It also made it easier for us to use the gravity drain and makes for very quiet operation. We use the ice throughout the day every day and absolutely love it. I have a water tap from my iSpring drinking water filter that I use in combination with the nugget ice which makes a great glass of ice water. This machine makes great ice for any drink or cocktail. It's also very handy any time we need to ice down a cooler. This ice seems to last better than regular ice in a cooler too, probably because it's small size fills every nook and cranny. Price is crazy, but if you can justify it, you will love this added treat in your home. 

Note: I clean the unit annually with Scale1 cleaner diluted 40ml cleaner to 500ml water in a squeeze bottle. My unit doesn't really seem to need cleaning, I think because I filter the supply water, but I do it anyway because it only takes about 40 minutes and is a really easy DIY job using the instructions that come with the unit.
