As has already been said, there will always be rule tinkering and model updates and like all tech, prices of older models fall as new stuff emerges.
I suppose it always depends on what you want to do, what features you need (or fancy) and how much you want to pay.
There are many great drones available with superb tech providing a hugely enjoyable flying experience and brilliant video and photo recoding. I went for a second hand Mavic 2 Pro though I must admit the camera can record at high def resolutions our telly can’t even handle - so I could have saved cash by buying something with less tech that would have been perfectly fine (though I’m glad I didn’t as I love the kit).
If you do decide to take the plunge, try to get the best you can afford which meets all your needs and remember that a battery charge will only give you 25mins flight (or so), so add-ons (like the fly more sets) with extra batteries are really essential. Likewise add in the cost of a decent case and make sure you have a phone or ipad which is suitable for use with the drone.
There is loads of advice available on here so just ask if there’s anything else you need clarified.
