If I understand what you mean by a "Buffalo" chopper, you mean to be able to high speed chop or slice vegtables etc. I beleive that they are quite pricey unless you find a beaten and abused old one. I would recommend that you consider a Kitchenaid Stand mixer and the add the slicer/chopper attachment. Or you can add a meat grinder, grain grinder and many more uses. It truely is a versatile machine worth studying before you buy. Hope this helps...Pst :)
