title_body: What are important factors to consider for a bean-to-cup machine?
upvoted_answer: Some major factors for consideration:
  1) Manufacturer and warranty - with more integrated parts I've had to return or replace my fair share of these (and finally moved to separate machines for better taste and performance at the cost of convenience).
  2) Capacity - how much are you brewing and for whom? 
  3) Adjustability - ability to vary the grind based on the bean / strength of coffee you desire.
  4) "Cleanability" - how easy is it to disassemble the machine to clean it - with these integrated machines it is essential that you break them down and clean them frequently to maintain good taste and performance.
