O2 sensors

I'm about to sell my '98 Taco. Te check engine has been on for a while, but it's been running fine, and fuel economy hasn't suffered, so I havn't worried too much about it. Since I'm about to sell, I had a friend check the code. Looks like an O2 sensor. Just how much of a pain is this to fix?

Shouldnt be to bad I replaced both of mine on my 01 Tacoma v-6 all it was was two nuts and a plug to undo. But dependent on how rusty your exhaust is and how your generation of tacoma is setup it may be a little harder. But again it shouldnt be to bad.
