I researched this purchase a while back and found that you can get Hobart slicers really cheap (<$300) from Craigslist and used restaurant supply stores. Restaurants go out of business all the time, so there is a very active market for used equipment.
Having a Hobart is a really cool idea, until you realize you don't slice meat all day long, and the thing takes up a ton of space and is really heavy to be lugging up from storage in the basement to the kitchen when you want it!!
