PB machines or not

Hi. At the age of 82 I decided to take up the game and love it. We have a small club of about 80 members that ha e been most gracious to play with a beginner. I think I would become a better player faster if I had access to a pickleball machine, and am considering purchasing a used one if one can be found. Would appreciate any and all of your opinions on this. Thx in advance, BuckeyeMac.
