Hope this will help me and possibly someone else that's just getting into the lighting part like we are. And hope I am making sense as well 
Here's what we need, we need RF (radio frequency) or something that will allow us to trigger multiple flashes that is NOT in line of sight. Some houses we do are large, and we need to light up, lets say a bedroom, hallway etc. But the flash will be completely out of sight and IR will just not work, or the lights that are triggered by other flashes. Also, we don't always do RE photography. I've read where another photographers (like at an event etc.) flash can trigger your flash and we don't want that.
Now I'm not taking the easy way out (Err kinda maybe!!), so please don't say that or take it like that, not sure if it happens on this site but others it does. The wife and I have been reading and reading. And we've done so much goggling, that some answers that we've read we cannot find them for the lives of us now! And the technology is not compatible with others etc. We don't want to run into any of that.
Again, please keep in mind that we just don't do RE photography. We want something very bright when needed but want to be able to turn it down if needed. We figured we want the max of 4-5 flashes. The line of sigh or flash triggered (slaves I believe it was?) will not always work for us.
We were going to get the kit from B&H with the Canon 600 EX-RTs and the transmitter with the umbrella stands etc for $1,300 but I've read you do not have to spend that much to achieve what we need to.
Can someone please help us out on this? I read where these "Yongnuo YN560-III Speedlite" will be good for us, and of course since we've been all over the webs I cannot find where I read that to get the rest of the info and tried to find it and cannot for the life of me.
I just do not want to make a wrong purchase of a grand + than find out we need to spend XXX amount more. I just want to make sure we get what we need the 1st time and if we can save some money, than that would be awesome because we need to also get a Glidecam and some video LED lights, microphones as well. And trying to see if I can work that into our current budget.
We shoot with a Canon 70D if that will help, if there's other info I left out please ask....
Thanks so much everyone.
I know about that section, but was wanting to stick in this section since the RE part is where we will not be able to have line of sight and wanted to hear what other RE photographers were using. I'm sure they will be able to help me over there, but felt better asking in this section since its dedicated to this type of thing.
