I have eachine ev800 (no dvr, 49 from a flash sale on banggood) a wolfwhoop wt03 camera, and 4 1s 250mah batteries with a charger and I came in under a hundred bucks.
The eachine goggles are the best "cheap" fpv goggles you can get from what i have seen. I took a gamble on the camera and it worked out. It works within a 200 yard radius, which is all I need it for. I wanted to try FPV without going all in and this worked successfully. I can add a dvr for 20-30 bucks later if I want.
