Those will likely work if cost is a huge issue. Those are previous generation technology, they are the ones I hate the most because tplink just renamed the av500 to av600 to try to trick people into thinking it was using something called av2-600.
You might see 60-80mps with units like that. You want to look for units with number 1000 or 2000. These too are a complex mess of lies but these tend to all be one of the newer technologies. You might if you are lucky get 300mbps but it depends on your house and the electrical wires.
