My fav are Double K's also. My mom owns a pair to use on her minis and I use them on my big horse whenever I get a chance. I personally have Oster Turbo A5s and they work on my horse but they would not hold up to a mini. The ony drawback of the Double K's is that your blades get very hot very fast and you need several sets of blades availible in order to change to hot ones out for cool ones. Dropping them into rubbing alcohol helps to cool them quicker. I have had some cordless Wahls and never had much luck with them, they just don't hold up or have enough power.
