I think the Makerbot requires filament cartridges sold by the maker that cost app. 30% more than open source.
You might look at a Robo R1. It can use almost any filament, has a 8"x9"X10" build area and is plug and play.
Even comes with the open source softwhere on a thumbdrive. I am looking at it now, will probably get one.
Check it out, Frank

PS: It cost $799 US
