Could you please point me to a link for the high tensile knotted/woven galvanized fence 8' high?
The brand of fence I used was BEKAERT SOLIDLOCK. You can get it with the regular shiny galvanized or a black sort of anodized/galvanized/painted coating. I went with the black because it looks a little better, but they both hold up the same over the years. Black might even be a little tougher. Only a few dollar more for the black.
Check out the suppliers others have mentioned. But try to find someone near you where you can pick up or the shipping will kill you. I only know of few suppliers in the northeast. If you're using wood posts definitely go with round. When I was doing mine there wasn't much dollar difference between wood or heavy duty galvanized tee posts. I have a feeling wood may be cheaper today.
If you want to spend less you can try other things first. I got by for quite a few years with just several strands of electric polywire and 3/8 fiberglass poles + a few tee posts or 4x4 at the corners; put up and take down each season, about 18 acres vegetables. Now I have ~25 acre inside the Bekaert. Another alternative is plastic fence, like Cintoflex P.

If there's other things to browse on in the area the electric fence may keep them out, but you want to have it fenced before they get a taste. If you don't mind maintaining electric, a high multi-strand electric high tensile would be cheaper that the woven knotted wire.
I've looked at quite a few fences in the area, some professional install, some DIY farmer. The pro ones usually hold up OK, the farmer ones range from excellent to schlock. The main thing with high tensile is proper corners and proper tension. With good tension you only need a line post every 20 ft. It's hard work to handle a 8 ft fence roll and you really have to stretch it with a tractor, a bobcat or several comealongs. Once the fence loses tension the deer will push on it at the bottom and bang the top when they try to jump. That's why with the plastic fence they usually anchor it at the bottom.
The USDA NRCS has recommended specs for high tensile or regular fence that you can Google up.
Wow, I was shocked how much metal fence has gone up in just the last 5 years; like 1/3 increase??
