The man said 'possibly horses'. I'd never use T posts for horses because they learn how to walk them down and if they jump up to chase a fly, they will get punctured. T posts will need to be electrified for horses. That 10 acres of WORKING electric fence.

Barbed wire never stopped a horse until its too late. If you ever board other's horses, they will probably reneg when they see the wire. My treated landscape timbers have lasted 15+ years, even the ones in the swamp. New pallets I just purchased to run some lanes in my fields went for $1.50 a piece from Lowes last fall. That's a lot cheaper than 4x4's or 6' cedar, You set the landscape timber so the strong side is out, not sideways. (Yes, I've seen the geneous side of civilization).
