If you want a high quality softbox for speedlights, I can recommend the Westcott Apollo in both 28" and 50". I have both and they open/close like an umbrella, are durable and provide wonderful even light
. The 28" come with a stand for a little over US$100. You can find much better freight options than retailers in the USA offer, just need to look around. I use a broker and save a packet buying all of my gear from offshore. The broker will also help you get around resellers that only ship to the USA.
