So long as you use the knuckle protector it's just as safe as a food processor, it's easy to set up and store and it makes great slices (or juliens, etc.). This one is by OXO and sells for around $70. OXO is the brand of kitchen gadget's the Alton Brown uses a lot on Food Network.
The big thing I'm coveting now is the Cuisinart Griddler. It's like a George Forman grill, but also works well as a panini press and, unlike the Foreman ones, it can open out flat and be used as an indoor flat grill. It also has flat plates to swap for the grill plates and can do things like pancakes. It's about $130.
