Bought 8 piece set and they are great.  Then I bought 2 more storage cabinets to go on each side.  Unfortunately, it cost more that way.

However, I learned a simple but important lesson.  When you are installing cabinets that will span 10', 12' 16' and the cabinets have leveling legs ALWAYS start out by putting the leveling legs of the first cabinet in the middle adjustment setting.  This way you can move adjacent cabinets up or down as you continue to add.  I started with the leveling legs all the way up and then found out that the floor rose slightly in the direction I was adding cabinets.  It sounds like it would be an easy fix by just going back and lowering the first cabinets, but they were already bolted together and bolted to the back wall.
