Suggestion for laser printer with affordable Toner?

[Bronkus]

Looking to buy a new laser printer because my Lexmark uses $250+ toners. I need something capable of 15,000+ per month that has affordable toner. Please make a suggestion of a good printer for me. It will be used in a law firm. Something new and not outdated would be nice.

I'm not a huge Lexmark fan.

Thanks
