I will PM you so this thread doesn't get clogged up with 'lesson chat'.@patricks148 is correct in his ideology.
Yes - it is legitimate to have an interest in equipment and trying / buying new clubs, but in reality the chances of this genuinely saving shots is slim.
I've not seen you explaining your reasons for not having lessons, but I would say someone who is a regular player at 20 handicap will have excellent capacity to improve with 3 or 4 hours worth of lessons and a practice session every week or so. Probably this will be far more satisfying.
Far better use of your money (and time) if you are genuinely looking to improve. If you are happy at 20 and enjoy playing and tinkering, then that's clearly great. But if you really want to improve and get well into the teens, I believe lessons will help almost any player in this regard - especially higher handicap players.
I started in 2011 and got fed up only getting down to 24 and playing rubbish golf. In the winter of 2013/14, I had 7 x 1 hour lessons and a regular range sessions. I year later I was down to 17. Barely spent anything on new clubs since.
