I've been using a wahl iron horse clipper for the last few years and I think it's time to retire it. I'm clipping for shows, so I'd like something that I don't have to take a break halfway through, but I'm not clipping a barn full so I don't need something that can do 20 horses in a row. I like that I don't have to change the blade to do close work and I don't think the better clippers let you do that. Also I have small arthritic hands so I would like something lighter and easy to handle. What do you all suggest I look for or stay away from?
