I understand your frustrations as there are loads on the market but here are my suggestions, I will try keep it simple not to confuse you with too many options.
Currently I would say the vortex 250 Pro is the best FPV quad on the market as it has excellent performance, and the software customization make it intuitive to use and setup, but its also one of the more expensive options but does not include a radio transmitter, as its not RTF. For that I suggest you consider the Frsky Taranis, along with an X4R receiver to use with your vortex. This is the one I would purchase if its within my budget.
But if that is too expensive I can also offer some other cheaper alternatives, one would be the Falcon 250, or Falcon 180 which is also nice, but not as nice as the vortex.. But these are totaly ready to fly and include all the parts you need. Just let me know your approximate budget and I can suggest the best kit we offer within that price.
