I have these clippers:
Andis UltraEdge AGC Super 2-Speed Animal Clipper - Dog - Sale Category - PetSmart
I also bought another size blade but actually never use it. Mostly for shaving areas like the ears or feet, I just use a little battery operated man's clipper and it works really good on mine. You also need to buy the combs as well. I did buy mine on amazon and it was awhile ago so didn't spend as much as it's showing now but good clippers are expensive....
