I hadn't heard of it until you mentioned it, but apparently Ken Lawrence is a bassist himself, and founded a company that makes guitars and basses. Here's the Wikipedia article:

Now as far as ordering one, that might be a bit difficult. I've never seen these particular basses online where you can order them, or in Guitar Center. They seem to be one of those rare, but great, and expensive, brands of bass. Here is the only site that I found that actually carries and sells the basses:
http://www.clubbass.ca/instock.html
That is a link to what they have in stock, but the also have an overview of some other Ken Lawrence basses here:
http://www.clubbass.ca/lawrence.html
So I suppose they carry all his stuff, but right now it looks like they only have the Chamber Bass in stock. The bass in that video you were talking about looked like the Associate Unity bass in the above link. So what I would do, is look around on that site, give them a call, and see if they are getting them in stock. If you have a wallet deep enough to afford something like that, anyway. I sure don't; Wish I did though. They look really nice, sound nice as well. Hope this helps.
