Need new Coin-Operated Laundry for Rental Property

Hey everyone, I am a landlord of a 4-Unit Building in Grayslake, IL 60030 and a 3-Unit Building in Chicago, IL 60607.  My coin-op washer is broken in Grayslake and is old.  I need to get a new option.  Does anyone have any recommendations for places to purchase and/or lease laundry machines that are reliable and affordable?  Also, does anyone have any recommendations as to whether they have found leasing to be worthwhile?  I know it is giving up revenue (we make about $75 a month at the Grayslake Property on Laundry) but I am thinking that the elimination of having to purchase the machines and the ongoing maintenance and coin collection might be worth it.  The property is about 75 - 90 minutes from my personal residence and I do not use a property manager.  Any help is appreciated.
