Dan I am:
There is a lot of original LC 30-06 floating around. This is original USGI ammo that has been delinked. I shoot quite a bit of it (30,000 rounds last year) and it's pretty good ammo. It can be found for less than a quarter per stick. At present, it's much cheaper than .308 or non-corrosive 8MM.

The Greek ammo is OK, but as log as the USGI stuff is available, it's your best bet.
