As someone who just started FPV a few months ago, I would recommend you look into Tiny Whoops.
They are pretty cheap, very robust (can take a lot of crashing, which you will do a lot of!), replacement parts are pretty cheap when you do eventually break something, and you can fly them indoors during the winter (or if you live in a no-fly-zone like me) which means you get lotsof practice time.
I started out with a DJI Mini 2, then met up with a bunch of people at the Waverley Abbey meetup and realised that FPV looked like loads of fun. But all the kit seemed intimidating, as did the sheer power and speed of the 5" drones.
Then @lbrou showed me his tiny whoops and it all made far more sense for a newb. A few weeks later I was the proud owner of an Emax Tinyhawk 3 Plus RTF (ready-to-fly) kit I got from ebay for £85. Frame was a bit bashed but flew fine and has been a great intro. As I was initially just flying indoors I mixed sim time with just trying it out indoors. I crashed a lot but only from a couple of feet up or at low speed so no biggy. I had to work on fine control but then when I did get outdoors it came pretty naturally.
What kit? The Tinyhawk has been a great intro, but I soon wanted better goggles (see the uavfutures review, I have “old man eyes” so needed adjustable lenses). Took the recommendation from @weirdmunky and bought a pair of Skyzone 04O and they are great, albeit they cost more than the full RTF package.
This is all analog video. Digital looks awesome but much more expensive to buy and repair - I knew I would be crashing a lot (still do) and so am saving that upgrade until I am more competent - analog is still a great way into the hobby.
On that front - repairs have also been pretty cheap. I damaged the camera, replacement was about £20-25. New props - £5. Burnt out a motor, got two for £18 although they took 2 weeks to get here from China. Batteries (1S) are about £4 each.
Couple of small niggles with the Tinyhawk: the props stick out below the frame, most have the frame below. So while it has “turtle mode” to flip over if you crash upside down, if you are on grass it tends to get in the props and won’t take off. And the video range is not great.
As I have been a good boy I have asked Santa for a Mobula7 as upgrade - very similar form factor to the Tinyhawk (I’m happy with the size and power still), but fixes those niggles. Also a Radiomaster Pocket radio - the Emax one is actually okay but radio is a pretty cheap upgrade, your big bucks with analog will be goggles. If they both turn up I will have replaced all of the original kit (drone/goggles/radio), but radio/goggles are still compatible with both drones so I have a backup.
So from my recent experience: Tiny Whoops are cheap and loads of fun, decent goggles are well worth the investment, and watch a bunch of YouTube to learn all about batteries, antennas and a host of other weird acronyms that come with the territory!
