I have the wahl Chromado & have been buying my blades locally. I paid $200 for the clipper and $45 for each replacement blade. A friend picked up a blade at Nationals year before last and paid $25 for it--but the chromado takes the adjustable blades & so I guess they cost more than the ordinary pro series blade above. At least I get a lot of clipping out of that one blade--I do a lot of clipping with my Chromado and only need one blade per year.
$15.95 doesn't seem like a bad price; wish I could buy mine for that!
