You can do basic FPV with an all in one camera and VTX ($30) and a pair of Eachine EV 800 box goggles, $45. That will have plenty of range for sport flying and give a fairly decent analogue goggle feed.
You will need to connect the camera to a 5v filtered supply, so you will need to add a separate Bec (soldering) or a servo plug to take power off the 5v/ground of a spare channel in the receiver. You can do that with a servo plug, which has crimp on connectors like JST, no soldering.
You can mount the camera on a servo for a moving panning camera, or if you buy the $70 Run Cam Split set up from FT store you can have a servo controlled FPV stack which records 1080p 60fps as well.
Soldering is an essential skill for model aircraft building, it’s not hard to learn and if you practice on scrap wire and plugs, cheap too. A basic 25w Weller iron will do great. Avoid cheap ones, they are awful.
