Long Ethernet Run - Copper or Fiber?

Hypothetical question:

Let's say I had to connect a pair of IP-based devices which are 800 feet apart, outdoors. Assume a wireless link is not possible, and that bandwidth requirements are in fact minimal.

Would it be easier, more reliable, and/or cheaper to use Cat5 twister pair, with an active repeater box every 250 feet such as this:

... or would it be more preferable to run fiber optic cable with a transceiver at each end?

Again, this is to reach a few low-impact devices so I don't need high throughput as long as it's reliable. At first I feared Ground Loop issues with copper (I grew up in the audio field) but it appears my assumption was wrong as twisted-pair is transformer-isolated and therefore immune by design. But I also suppose that fiber would eliminate any RF issues as well as minimize catastrophic losses due to static electricity or lightning.

Am I missing anything that significantly points to one or the other?

Thanks!

I'd go with fiber but it's likely to be more expensive.

If your budget allows, go with fiber.
If not, then use CAT5/6 and ethernet extenders

Not sure which I'm going to do yet but I think I have all the information I need. I may actually go wireless but wanted to at least have a good handle on wire/fiber options due to less security risk/management.

Thanks!
