I have been using the Wahl Arco Se(which I like), but I think I need something more heavy duty. I want a clipper that a pro could use for anything. Something I could use with a metal comb and do a retriever clip OR use for clipping into a continental, etc. I also want to get metal attachment combs for my new clipper because the plastic ones have never worked for me. I am looking into the Wahl Arco. Those of you who have this clipper, did you need to buy any other blades eventhough it is an adjustable blade? Also, I didn't find metal attachment combs specifically for this clipper?
