I have a EdgeCraft 610 Chef's Choice Premium Electric Food Slicer
I am pretty happy with it, very easy to disassemble and clean. I bought the optional non-serrated blade which enables thinner slices. My use is relatively light so I can't say how durable it is (most I ever did at one time was 15lbs of top round). The comments on the web site I bought were mostly positive.
One of the recurring negative comments on this (and most other) slicers was that the motor would bog down and either overheat or the gears would break (this unit they are nylon). My personal opinion is that those folks are pushing way to hard trying to force the meat through the cut. I have never had a problem but I let the slicer do it's job, take my time. The non-serrated blade takes a bit more time to cut.
I paid about $120 for the slicer and another $30 for the non-serrated blade.
