spend at least a week looking at this forum, and this one:

Before buying anything.
Your middle link is dead.
The bottom system will not give you 1000ft, more like 50-75. Also, the cameras on the top and bottom are both cmos sensor cameras, which are not good for flying.
Take a look at what is sold by site sponsors, it's usually pretty good. If you find a system for sale, but don't see someone here or on another forum flying with it, especially if it's under $200, don't buy it. We have spent a long time buying and trying stuff out. There is no magic sub $200 solution. Expect to spend around $350 -$450 by the time you get something working well. If you don't have that much, save your $$ for a while. Buying a cheap system will just delay the day you have the $ for a real system.
Most everyone powers the rx with a battery. Make sure the voltage is right, but most are pretty tolerant.
Best of luck
