I've installed several cabinets by building and leveling plywood bases, and I just installed a set of kitchen cabinets by shimming each cabinet independently (since they had toekick spaces cut out already). I'm about to build a set of cabinets for my basement and given my experience with previous approaches would like to try leveling feet. The ones at Rockler or Lee Valley look pretty similar. I've also seen people mention a brand called Camar and I was wondering if they supply Rockler or LV. So my question is--are all of these pretty much the same? Is there one type that is easier to work with or install?
