What type of office copier is best?

My boss is having me look for a new office copier and I wanted to know if anyone can give me specific brand or type of copier that you have had excellent experience with. I used to work at a different company and their copier was extremely fast, which is ideal and very clear. Our copier now also gives us free toner whenever we run out, that's not the most important thing, but it would be nice. Your advice is greatly appreciated.
