What is better for trimming fur: scissors or cheap pet trimmers?

I did some hunting around the memories and past entries, but I'd like some more information. One of the last things I need before beginning this project is a way to trim fur, but my budget is $30 or less. I could get myself a decent pair of scissors and maybe even a sharpener for that price, or I could get some super cheap clippers. I realize I won't be getting a brilliant cut out of the clippers, but the idea of buzzing through fur is so much more alluring than hours of snipping. Which is the lesser of two evils?

Also, for those of you who use scissors, are pet scissors preferable to hair scissors? Are you aware of any tutorials (or even good keywords to search) for cutting fur with scissors?
