I have used pretty much every type of Andis 2 speed clipper; and own about 6 Andis clippers, including a cordless one; my oldest clipper is 10 years old...other than replacing the housing, switchplate, and a 'few' drivers over the last 10 years, the thing has held up through horses (which is what I originally bought it for), goats, dogs, cats, and even a couple of sheep! My 'newest' Andis is the UltraEdge I bought last year; not necessarily because I needed it either...just cause I wanted to add another one to my rotation at work.
So...yeah...go with Andis...
