I started off with a heavy Wahl clipper that cost me about $110 but it was loud and it needed various blades depending upon how short I wanted to cut the hair. After that I got a rechargeable Andis clipper that also had an adjustable blade, which means it adjusts from a 9 to a 40. It has snap on combs if you want the hair longer. The clipper is much quieter and also much easier to maneuver it in tight spaces. Ashley was so much happier when I used that clipper. It's pricey, but I'd really recommend something like this. I love mine!
