@cloudel - I would say that my office is medium-sized, but we benefit from managed print services as well. We have a huge scanner that would have cost a ridiculous amount to purchase, but we lease it for an affordable rate, plus we get the added bonus of service calls.
Our copier gives us issues more than our other equipment. However, the company that we lease it from is located just down the street, and often they show up on the scene within minutes. We rarely experience any significant efficiency loss because of this. I would recommend it for any office other than a huge corporation with tons of money to spare.
