Sure you can buy from SF direct - did so a couple of weeks ago but there is a catch.
They do not have a showroom or any other place to display their wares. You have to call the order in and tell them you want to pick it up.
Since you live in L.A., if you call by 10 AM your order will generally be ready at Will Call the following day. SF will call letting you know when your order is ready.
On a side note, many have remarked how small SF is once you get there and see the place. That really isn't the whole story because not everything is done at that site. They have a couple of other turning facilities in nearby cities.
