Start off with the $15 cheapies like the E10 and solder a small TX03 camera onto it followed by Lizard95 and similar sized drones and then onto larger 180-250 size drones like the Wizard x220s.

For the goggles I'd recommend the Eachine VRD2 if you're cheap or Aomway Commander if you want low profiles.

All can be found on banggood.
