Forget human clippers and the (useless junk) clippers sold in pet stores. If you're going to groom at home, you need the proper equipment that's going to get the job done.
I paid $124 for my Andis UltraEdge 2-speed clippers. I love them! I was used to the very light, easy to handle Wahl Arco cordless trimmer, so found all other clippers I handled to be heavy and cumbersome to use. The Andis UltraEdge is the bomb!

It's easy to handle and use, doesn't get hot, fast, like some. I used the Arco to do face, feet, and tail of my Standard Poodles, and also use it to shape topknots, the latter discovered when I had misplaced my shears. I took them to a professional groomer every 4 weeks, but liked them to look "perfect" in-between, so figured I could do the FFT easily enough. I found out later that I was actually doing the most difficult areas to learn! LOL So, invested in the Andis clippers, and the rest is history.
