Let me offer a different perspective for you. I have been shooting for 50+ years and have shot many different recurves over those years. I have owned and still own multiple one piece bows as well as takedowns. I like them both equally. Some of the takedowns are as aesthetically pleasing to me as the one piece bows. What I think you should be looking for as a beginner is a bow that fits you. I find that the grip is the most important factor in the ability for me to shoot a bow well and enjoy shooting it. You should be trying high wrist grips, medium grips and low wrist grips to see which you prefer. Then you should see whether you prefer a blockier grip versus a slim grip. Some people like grips with a thumb rest (I don’t). I have even found some grips where my hand just never feels good and I get pressure spots on certain fingers. Mass weight of the riser is another factor. Some people prefer a heavier weight riser, some want a very light bow. I find that while I can swing a lighter bow into position for a shot quicker, I prefer a medium to heavy riser because it is steadier for me at hold and release. Other people will have just the opposite opinion. The point is that you should try as many different types as you can before you settle on one. You will get to a point where you put a bow into your hand and know immediately that it just “fits” because it feels that good in your hand. Then of course you need to shoot it and see how it performs, how much noise it makes, how twitchy it is, etc.
I agree that the classifieds here is a great way to start. You could buy one and if you don’t like it resell it and try another until you find the one.
