We've received three different bids for installation and they are just more than we really want to spend right now. I'm thinking of doing it myself. I have a friend who put his own fence in about 10 years ago and he says it's not too bad. So, for a guy (me) who has mediocre (not fantastic, but not horribly poor) DIY skills, is it doable? If I do it, any tips?

Mods: I'm not sure best category for this. Sorry.
