I will assume you are a senior gent like me. If you like golf then get the new sticks and play as much as you can. Get fitted, have your swing looked at first, try a few things out. Spend some time getting up to speed on it all. Spend some money on yourself. It's time to treat yourself.
Once you get your knee fixed get on the golf project, and now you can educate yourself beforehand. Waiting does not always save money. A new line of equipment comes out and the price always goes up. Since you are 25 years behind the technology look at last years models to save a few bucks - you wont be able to detect any difference. You will love the new equipment and it will be much better than what you have, but don't buy the lowest line. Look for quality and value, but mostly quality.
Edit: I see you added a few more post and you are not a golf rookie, so you know this already. Enjoy!
