What is your favorite pair of hair clippers?

I've used a Wahl (the one that has the color coded guards) for years and it worked great, that is until a couple of weeks ago. Went to Target and bought a new one, $20. There's a night and day difference in my old one and the new one and not in a good way. They're basically nonfunctional, I can't get the blades to move unless it's extended all the way out. I've oiled the damned thing, took it apart and cleaned it (although it's 2 weeks old I should have to), etc. Still sucks.


So it's going in the garbage, what should I replace it with?
