title_body: What are the best single shot filter baskets
upvoted_answer: Welcome to coffeeSE!
  
  I'm not ready to invest in a more expensive grinder, should I even bother with a precision filter basket/differently engineered basket?
  
  No, do not bother with precision filter baskets. The Baratza Encore is definitely not a grinder for espresso, it is meant for brewing methods which use coarser grinds like filter coffee or French press. It cannot grind fine enough properly - you get an inconsistent grind. Baratza offers the Sette series which grinds fine enough and consistent enough to get good espresso. I really wouldn't recommend buying a high end basket until you have a proper grinder, maybe look for used grinders. I got mine super cheap because it was used and after a proper clean it was almost as good as new.
  One rule of thumb when getting into espresso is to spend at least as much on your grinder as you spend on your machine.
  
  If so, what are the aspects to look for? What are the models to consider?
  
  If you really do want to experiment with a high precision basket, just look for one which fits your portafilter (shouldn't be too hard since you have a standard 58mm one), is big enough for your desired dose, and is from a somewhat reputable brand (and is ideally used by professionals).
