I don't think there's a "best". I think what you're seeing is "meat" slicers. By "meat", they mean lunchmeat, not steaks. The major manufacturers will "grade" their slicers as for what they should be used for. For $500, I don't think you're going to find anything "new".
Here's a guide by Berkel for their products. I'm not endorsing a brand, just pointing to a resource.

Here is the 825A for $800 with free shipping. According to Berkel, this should handle 2-3 hours of cheese slicing per day as long as it's under 7" diameter, which I'm pretty sure the block you're using would be. Again, I'm not endorsing a retailer, just providing a resource.

I have NO affliation with either company; I'm just trying to provide some examples.
