Can't go wrong with Wahl. They have sets ranging from $25 (us) up to $250. They also have professional pieces that are upwards of 250 for 1 such as T-Liners if you're looking to spend that much. I usually buy the $40-80 set ups and they last for about 2 years before needing sharpening, replacement of blades, or have a slowing motor. I cut my own hair every Sunday and recommend always keeping the clippers oiled.
