Eli51: You’re incorrect about the “only” DD with a reliable hechsher. In Teaneck there is a DD under the RCBC, and in Elizabeth there is one under R’ Teitz shlita. Both the RCBC and R’ Teitz are reliable.
As for Joseph’s post about shas hadchak, he’s incorrect. That letter was not printed in the Igros Moshe on purpose (while R’ Moshe zt”l was choosing which tshuvos were published) because it didn’t apply to the general public. It was a letter written to a yeshiva which had been serving only chalav Yisrael, and due to financial hardship, asked about switching to chalav stam. His reply of only b’shas hadchak does not apply to most people.
