That $600 was at one place. I spent about $400 at another too (each has some things cheaper than the other.) This fence is really just for the goat and pigs. Will use only 300ft of farm fence.
The horse pasture I did a couple of months ago was about $4k in material. Have another a bit bigger to do later this month/early next month, but will be using electric tape instead of no-climb so it should be a bit cheaper though it will be a larger area.
So I'm thinking...sounds like you have enough room to use those 25 ft. miniatures...
