Veggie/Fruit Slicer

Does anyone have a good vegetable or fruit slicer that they would recommend?

I like to slice cucumbers really thin to eat, and would love it if the tool could do that. I've gotten pretty quick at slicing them by hand, but I would love it if their was a good tool out there that could make it quicker and easier.

I would also think a tool like this could be very useful in preparing fruits and veggies for being dehydrated and preserved.

Any recommendations?

Not adjustable, but so easy and efficient.  WearEver food processor:

My aunt has a mandolin she loves and says makes her life more efficient. I'm the type of person who would slice her hand more with that than just chopping with a knife. I have a cuisinart food processor that supposedly also does the chopping well, but it is too much drama for a simple chopping. I just use a good knife, a knife sharpener, and a few cutting boards.

For a quick slicing of cucumber normally I just use a cheese slicer, you can slice a whole cucumber in less than a minute and the slices are all the same thickness.

Edit: Perhaps I should mention which cheese slicer, it´s the Boska Milano. This is the best allround cheese slicer there is imho. It will slice consistent good slices which are perfect for sandwiches and should last you for decades.

I use a meat slicer when I do cucumbers for pickling, I don't turn the slicer on just use it totally as normal but with the blade not turning, it works fine that way!
