I have the O-Cedar, too - and not only is it cheaper, you can get it locally like at Walmart and went ahead and bought an extra mop head at the time I purchased the mop set. I like it - wish it could squish out just a tad more water, but we have tile floors and I just go over the floor with a towel (propelled by my foot) and it dries in just a couple minutes or so. I like mine. :-)
