I was in your same shoes 20 months ago. Looking to get back into the game.
I almost bought a cheap set of new clubs when I started but I am glad that I didn't. The used clubs that was able to put together have been more than good enough. And now I am at the point that I want to start getting new clubs so I am glad I didn't waste 300-500 dollars.
Once I started playing I figured out quickly what I wanted vs needed. I was using a old driver and was
embarrassed
to even use it and
desperately
wanted to go buy a new one. I had no wedges though so I picked up 3 top flight wedges at dicks for 80 bucks to complete my set and was ready to go. I have been playing the same set now for 60+ rounds and now am starting to put together a complete new set of clubs. If you can get a used set for cheap or free I would go that route.
