As far as I know it's quite expensive though I couldn't give you a price. Also I've heard various comments regarding the durability of powder coating. However I personally wouldn't go down the hammerite route either. I would be looking for a good quality durable paint which I'm sure some of the others on here would be able to recommend. On my rebuild I've been using 2k but I wouldn't use it unless you've got full air fed masks etc.
