We have the OXO chopper and can't be happier about it. Easy cleanup since the blade unscrews from the base and can be machine washed with most of the other parts. Only the plunger side can't be, but that normally doesn't have anything in it. Large or small portions and can do up to a cup. I bought it about a year before we got married and still have it with moderate wear and tear. Would definitely recommend it to anyone looking for a good all-around chopper.

I have something very similar to the Chef'n Veggie Chop - it's a small non-locking container where you spin two to three razor blades around. Looks like fun, but totally dangerous for a household with children, thoughtless husbands or "helpful" guests.

I use the mini food processor attachment on the immersion blender for the same purpose. Or, in the case of big jobs, I go for the big food processor. It save SO much time this weekend when canning salsa!

I definitely find chopping vegetables laborious, but I've never been convinced that one of these (or even a mini electric food processor) would be that much of a help--I just feel like by the time I've peeled/trimmed the vegs and cut them into smaller enough pieces to fit in the contraption, how much am I really saving myself...? Then again, I'm generally only cooking for two so my quantities are rarely that huge...

I have the Slap Chop (As Seen On TV), and it is very useful, but the clean-up kind of sucks. I hate chopping nuts by hand, though, so I use this for adding walnuts to banana bread or cookies. Beyond that, I think a knife is quicker when you take into account washing it, because you have to unscrew everything, try to get between the blades (tricky!), and then either dry it all (tough with all the nooks and crannies) or let it dry (it has so many pieces it takes up a lot of space). So if I am doing a ton of chopping, it can be useful, but I still tend to use my knife (plus I love chopping things up by hand, it feels more home-made with love!)

I've tried all three styles, but I found the alligator style the best. All others tend to puree or crush the products rather than properly chopping them. If I want to prevent the pureeing or crushing, I have to assiduously remove the smaller chopped veggies leaving only the larger parts that require additional chopping. This usually means a lot more hassle and frustration than just simply using a knife and chopping.

Even with the alligator style, I do not use it unless I'm chopping 2 or more onions.

I have the OXO Good grips chopper. It definitely is good, but I use it mostly for Onions. Since I hardly cook, and if I do, that too for three of us, I would prefer to chop rather than put time to cut it into small pieces to fit it into the chopper like "Brooklynnina" mentioned. Investing in a good chef knife and understanding how to use it could be of great help than gather chopping gadgets for certain type of veggies.

My chef's knife and knife skills are good enough where a vegetable chopper is unnecessary.

i personally really enjoy chopping most vegetables. i love cutting onions, cucumbers, etc. the only two things i really don't care to chop are tomatoes (maybe i just need a better knife, but i can't get them nicely shaped enough, hah) and garlic ONLY because it's small. other than that, i love cutting up my vegetables and i find these things unnecessary.

Just keep using the knife, you will get better and faster. I am amazed at how quickly I can mirepoix a whole load of veges these days. Fast knife skills make life much easier.
