As far as the HP blocks go, if you're skeptical, I'd wait until he had them in stock and ready to ship before committing. He said they should have a good supply by the middle of the year. I have zero experience w/ them, I just got curious this morning and gave them a call.
When I get mine in will be a good indication when he's ready to fill orders. I post as soon as they show up. I hope it will be soon!!
