Triggers? brands , numbers what a headache for me

I want to buy a pair to use my 580M2 with my 7D. Some days before I was shooting in a church and the wireless frrom Canon work OK but sometimes it was very dificult since I need to be or close or in sigth/angle with the flash
So I have read here a lot about this Tx and will buy a couple but still something I am missing(not intrested in PW for now)
I read here this review http://www.lightingrum​ours.com …-flash-trigger-review-691 and they only talk about this Tx but:
Q: Is cactusV5 the same and is not included here?
Q: if they are the same thing , which ones could be better.( Not planning to shoot more than 328feet(100m) away).
Q:It seems that RF602 is the standard here for low price wireless tx is there others as good as RF602 not included in the review?
Thanks

I'm waiting for the RF-603.

Rf-602's work flawlessly for me.
