My first choice is Double K's. However, they are more expensive and if you are not showing but just getting the hair off a couple horses for comfort then you have many options.
I love the Laube Lightening clippers. They are light and powerful.
For years I got buy with a pair of the Oster golden A5's. When I started show clipping 8-10 horses I needed something more.
For a quick, get the thick dirty hair off clip, the old Sunbeams are fast and powerful as well but they are heavy and you still need a smaller pair to get the face and legs.
What do you plan on doing with your minis?
