What size trays are you talking about?

What kind of freezer is this?

One thing to watch out for is that older full-size freezers ran the coolant through some of the shelfs. I don't know if any of the more modern ones do. If you have that kind, you want to be careful about not overloading those shelves.

He asked about 1000 cube trays. I have been trying to explain why he won’t find such a thing. Some of you seem to think I am being silly. So be it.

No one is saying that he can expect to find 1000 cube trays at the local five-and-dime. There is no conceivable consumer market for them. It's possible that something like that exists in the commercial space, but I wouldn't put money on it. Most commercial operations would quickly invest in an icemaker (which is something the TS might look into, as well).
