High res FPV isn't really viable for racing, especially on 250 quads. You want the lowest possible latency and HD video typically stays in the 100ms+ ranges. There are some lower latency transmitters, but they're extremely expensive and big, they don't fit on a racing quad.
If you have money to blow though, you can shop around for a good camera, though the one I see recommended most often, the Sony 600TVL Super HAD is not very expensive as such, but has good adaptability to light, which is pretty important.
You can grab a HeadPlay HD FPV headset, has a 800x1280 screen and HDMI in, so if you decide to later on give a try to HD FPV, it will be able to handle it. Also has an integrated receiver for standard analog video. This one costs $250. Cheaper solutions do exist however.
For the transmitter I think you can safely grab something Eachine from Banggood, it's not likely to make a huge difference. Research antennas however, they make a big difference.
For the actual quadcopter, you should probably consider starting with a cheaper quad because you're gonna be crashing a lot. If you have absolutely 0 experience with quads, I strongly recommend getting a bigger $30-$45 toy quadcopter from China so you can get used to their handling without breaking a propeller every minute. Alternatively you can just use a simulator but it's not quite the same.
Only if you are confident in your flying should you start throwing money at the quadcopter itself, if you buy brandname components you're gonna be finding yourself around the $400 mark for the body, motors, ESCs and battery. The same shit costs $90 from China.
If you don't have a radio, a RadioLink AT9 is a good value choice at around $100, otherwise you can get an FrSky X9D+ at some $250.
