What Vinyl Cutter Works Well With Mac?

I am very confused about vinyl cutting machines that are compatible with Mac...

I am looking for a vinyl cutter that works well with Adobe Illustrator CS4 on my Mac. I have worked with vinyl cutters before but never had some for myself. I want to buy one but don't know what is good and what is bad.

I see cutters for $300 and some for $8,000. I am just planning on making stickers for my car, snowboard, and sell some to my friends. I want to get something nice and not be crap but also want it to pay for it's self down the road.

What do you recommend? I am looking for a 24" cutter if that helps.
