I think you're talking about welded wire. We used 5' welded wire for our dog fence and it was around $50 for a $50 section. We did use wood posts (landscaping timbers) as they were actually cheaper than metal T posts (not to mention more sturdy/safer). You'll need to reinforce your corners regardless of whether you use wood or metal posts and find a way to stretch the fence very tight when you're putting it up (my dad rigged up some sort of a pulley gadget to hook to his truck hitch). It was very, very affordable and we fenced in over an acre.
With welded wire, taking it down after use won't be quite so easy (rolling it back up/transporting it would be a big chore), though, so you may have to resign yourself to leaving it up after you move on.
ETA: We got ours from Menards, a home improvement store similar to Home Depot. Here are some welded wire options from Home Depot: http://www.homedepot.com/webapp/cata...gry=SEARCH+ALL
