Softbox for off camera Flash

I've been made to feel a bit guilty by Nerf over at Flickr.com. He posted a link to this relatively abandoned blog and reminded me I should start posting again!

Something that comes up regularly in the Strobist flickr forums is soft boxes for battery strobes. The main branded one out there is the Lastolite Ezybox. This is a great little box with beautiful light. Strobist and EOS Magazine writer Gerard Maas does a bit of writing about it. It's expensive enough, but there are alternatives.
In the US market Alzo have an identical one to the Ezybox for half the price. Photomart in the UK also do an unbranded version of this box.

Personally I have 2 of the Photomart versions and really like them. I do like the look of shoot thru umbrellas, but using a softbox gives a very different quality of light. Here's a sample image with the softboxes:
