I just moved my cabinets to my new house.  I was going to use felt casters under the leg levelers to move them around the room, but then I noticed all 4 legs on one cab were bent to hell.  I'd rather just get casters for the cabs, but I don't know any suppliers to check out.  
From my research on BYOAC, it looks like people in the past have just used box store casters.  I could do that, but that would increase the height of the cabs by 3-4 inches unless I go with small wheeled units that are probably not sufficient.  Anyone have any ideas?
