We have a slicer that we bought at JC Penney on sale for half off a couple years ago. I use it to slice bread though. And those big sticks of pepperoni for homemade pizza. Other than that, the ones made for home use don't usually slice really well for meat. The reason is that the blade gets "dull" and doesn't slice as thin. The home use slicers don't have sharpeners on them so they never get back to that factory blade. Unless you can take the blade off and get it professionally sharpened, I probably wouldn't buy one. I love my slicer just not for lunch meat. We like ours to be really thin. A decent industrial size slicer starts at $600. If you have a restaurant liquidation center you might be able to find one there. But you will still pay over $100 for one. Can you tell I used to work with slicers?
On the other hand, we buy our meat from the butcher. He sells lunch meat too! Ours charges $4.99 a pound for the same brand that the grocery store is selling for $6.99! He even has prosciutto for only $7.99 a pound!!! I keep trying to find a reason to buy some. LOL So if you have a butcher in your area it might be worth checking out.
