Umbrella Starter Kit

I'm looking to just buying a starter kit. I want to have it as an option out in the field, or indoors. I usually shoot with natural light, but i figured i'd need an umbrella just in case.

Do any of you know of any good starter kits?
I'm looking for the stand, the shoe mount, and a shoot-through umbrella.

Are these kits any good?

Note: I'll be shooting with a 580EX II and Cactus V4's mounted via the hotshoe.

Any suggestions would be helpful!!

This is a good starting point for researching speedlight use. He mentions a westcott umbrella, but I'm sure if its the same on you linked to.

Of the two options you link I would go with the Westcott. Cowboy Studio gear is cheap. While that is not always a bad thing, you have a $400+ flash. It only takes one fall from a less than ideal mount to kill it. My cheap Yongnuo fell from a 8' stand w/ cheap umbrella adaptor and ended up useless. I now have Photoflex umbrella adaptors (arguably still cheap) and find them far more reliable and they adjust much more accurately. Nothing is more frustrating than aiming an umbrella and tightening the mount only to have it drop several inches once you let go.

Cheap umbrellas are great to learn with. I love mine. I have even had good luck with my cheap stands (without air cushion). The umbrella adapters and shoe mounts I would not skimp on....not with a 580 anyway.
