A great mandoline, especially for carrots?

I've read a bunch of reviews on mandolines, but none address my chief need: one that juliennes carrots well. I've tried the Japanese kind (Benriner), but I really didn't like how unstable it seemed, and I cut myself several times. Then I got the Oxo, because I usually like their products and I had read good reviews, but it did *not* work well for me. The one chore that makes me long for a mandoline is julienning carrots, and the Oxo just wasn't sharp enough for their toughness. A lot of the reviews I've read have people raving about how easy it is to slice potatoes, or zucchini... those things aren't difficult to slice anyway. I need something that will work like a dream on carrots, but I'm reluctant to drop a lot of money on yet another device if it's not going to work out. TIA!
