Still being made!
A few people have told me recently they can't find the car on the website for some reason. Click on kits, then BJ4WE at the bottom of the page, part number is 4100

Now comes with white ballcups, shiny CVD's and steel slipper T-nut as standard for $375 (~£250) if ordered direct. Cheaper and better spec'd than a B44
I'm not sure if/how many kits SMD keep in, but shops with an SMD account should be able to order a kit for you given a little lead time.
