Another Roomba 650 owner here! Mine was $280 purchased from eBay, in March. I also have a Roomba 555 bought for $200 in 2012. I spent about $100 to upgrade the older one to the newer sweeper/dustbin and to buy a new battery. Love them both! Could not imagine life without them. To press a button, leave, and come back to a parked Roomba with a full dustbin is glorious! The amazing thing is that they actually do a better job then using a broom and dustpan.
