Also check ebay. I have bought there as well as Amazon and Walmart.com, the prices fluctuate a whole lot. I got a super deal recently because the delivery date was like a month in the future. They actually delivered it much sooner. As much a shipping costs, I can't imagine they made enough to pay the wholesale price of the wire.
The wire gauge is directly related to size of the holes. 1/2 uses large wire than 1/4 inch. Both seem equally strong to me, with the lighter wire benefiting from having twice as many wires running across the same span.
I think any HWC is impregnable to predators except at the edges, that is always where any intrusions occur, so the size of the wire or the holes is far less important than how you secure the edges. That comes from experience. So focus your planning and spending on making sure it is attached securely and won't work loose in a year or 2.
