I got one of the low to mid range Cabella's slicer as a gift a few years back and it doesn't work worth a darn. It's a 10" I think and goes too slow and tears more than it slices. I don't have much need for one but if I were going to buy one I'd look closely at product reviews and spend a little more to get what worked.
This is an old 12" Globe I bought from a catering outfit going out of business. I think this thing could double as a wood planer. Go 12" for sure, whatever you buy.
