Current best sources for bolt heads?

[JeepsAndGuns]

So I have a 308 I will be soon changing over to 223. Naturally I will need a new bolt head. I have been searching around and so far am not coming up with much. So far the only places I have found that have them, are gunshack and PT&G. However, gunshack does not list the left handed bolt head for 223 (only 308, which is what I have), so really that only leaves me with PT&G.
The PT&G bolt heads seem nice, but they are a little pricey. Is this going to be the only game in town for what I need? (223 left hand bolt head)

Checked there before I posted this thread. They are out of stock. Midway and brownells are both out of stock as well.

The one I purchased seemed to be. I installed it as is and have not had any trouble with it since.

It was my understanding that on a rifle with a barrel already installed and headspaced to the old bolt head, and all you do is swap in one of their bolt heads, headspace will most likely need to be adjusted.
However if you are doing a new build, where you install the bolt head, then install and headspace the barrel, all will be fine.
