Thanks for the post. I researched these a bit more, and I am attracted to the price. Only $30 for the RF-603 trigger and maybe $70 for the flash. Much less than the Canon, and if I don't like it, I won't feel like I wasted much money on it.

1) I looked at the review for the YN-465. I wondered about the Guide number of 27 (vs 34 of the 430 EX II). Is this enough "power" when flash is diffused with an umbrella or soft box? I can get the YN-560 II for ~ $80 (, which seems popular. Do you recommend this one?

2) For the Umbrella (Impact 60") that you suggested, if I get this stand (, is that enough, if I have one of the Yongnuo flashes? Do I need a "bracket" like this (


Yes, the YN-560 II is a good choice if you want a bit more power.  As to whether or not it will have enough power the answer is perhaps. | Yongnuo Speedlite YN560-II Manual Flash (new upgraded ‘mark II’ version)

Normally I would be using at studio strobe with diffusers larger than about 24" (softbox or umbrella) so that I could shoot at ISO 100 to 200.  Typical hot-shoe flash units simply don't have the power of studio strobes so you will be trading off using a higher ISO, lower cost, and greater portability for the greater power and shorter recycle times of studio strobes.

To use hot shoe flash at f/5.6 to f/8 with a 43" diffuser you will be using ISO 200 to 400.  With a 60" umbrella you will certainly be at ISO 400 to 800.  Of course you can use two flash units in the same umbrella to gain a stop of power.  With a modern DSLR the noise at ISO 800 is reasonable and can usually be taken care of in post processing.

It looks like the stand and bracket are the same ones as in this two umbrella kit.  They are fine - I have a couple of the brackets I use all the time.
