I bought a 12-strand single-mode pre-terminated cable from fs.com. I don't remember if it's armored, but it is in conduit for the whole outside run. 12 strands was only slightly more money, and it gives me tons of flexibility and future-proofing—even if I'm normally only using a single pair. For instance, when I upgraded from 1GbE to 10GbE earlier this year, I was able to utilize a second pair to do the upgrade in stages (anything to avoid disrupting my kids' Minecraft server connections...).

I think the total cost for fiber and transceivers was under $200.
