Looking for some grooming advise?

I want to start grooming my Toy Poodle Baxter but I'm not sure what brand of clippers I should buy. I've been reading different book and watching videos but none really go into detail on what brand of clippers to buy. As a beginner I don't know if it would be wise to buy a pair of expensive ones or cheaper ones. I see Wahl a lot at different stores but when I look at reviews they're kind of mixed on how well they work. I was wondering if anyone could give me some kind of advise on the matter?
