I love, love, LOVE my Double K Groomers Edge (model 401) clippers! Did I mention I LOVE THESE CLIPPERS! The handpiece does not get hot, they are not loud or do they vibrate excessively. I own minis (obviously) and pretty much every other week all summer and fall I am clipping 7 horses. I have never once had a problems with them but they are not cheap. They will cut through ANYTHING, even on setting 3 and 4! I have sheared sheep with them and they are not even close to being a sheep shear. I am thinking I paid $320.00 plus shipping to get them here. If you clip on low speeds they leave almost no clipper marks and if you really take your time none at all! I have clipped the night before a show (full body clip) and you could not tell. Mine have the 12 foot cable and are the portable version. They can be ordered in many lengths from 5 foot up to 20 I think. I also purchased a hoof polisher, it is awesome too.
This is their website 401 Equine/Large Animal Portable Clipper
Depending upon the website you go to they are ranging from $320 up to $700. Do not pay $700 for them! The $320 ones are the same ones. They start there but the prices does go up slightly if you want the longer cables.
This is about the cheapest I found doing a quick search for them. http://www.groomerstore.com/clippers...Fcjc4AodU3hz5A
Sometimes you can find a reconditioned pair, Double K does all the work and they work just as great as new. If you see them somewhere priced reasonably do not think twice cause they will be gone.
