Anyone own or have opinions on this brand? I I'm going to check one out I found on Craigslist. The guy isn't sure of the model it it is a univex boston. There's a 6509 and a 7510 I believe. Only thing I noticed is that it isn't open behind the blade. Meaning there's a piece of frame extending down to the base and anything sliced almost looks like it has to do a 180 once its through the blade. He's looking for $200 obo and I'd really like one for doing jerky and lunch meats. The only thing I'm concerned about is how the meat is deflected after its cut. Anyone else have a Slicer like this? Thanks.
