There is a good selection of equipment on the site and prices are pretty good as well. It seems a big feature draw is the ability to create lists of equipment that you need for various events. I do like the system they use for further filtering your search results with links on the left side of the page, it reminds me of the system used on Puma's website -- BTW, I'd love a gi from them; I may need to create a Puma-based MA style to justify it. :-)
I cannot test Zengu's ordering system as I am not an owner and can't prove that I am one. They do restrict membership by having you send them a copy of your business license and a copy of a brochure from your school. I don't know how or if they verify this information.
Zengu.com looks like a great resource, espcially for the selection and pricing. There is more information on their site here and on the Ikigai Blog.
