They're both good, but I'd go w/the Oster.
Here's a really good home grooming clipper kit:
PetEdge: Andis Easy Clip Clipper Kit
It comes w/#4, 7, & 10 blades along w/combs. Right now they have 5% off $100 order :PSA5 ends today (12/18). They do have a minimum order or they charge a fee, not sure how much.
