I wish a $1,000 coop was ridiculous. But my BF and I built our coop ourselves, and we spent $500 JUST on plywood. (It's a 10 x 10 coop.) Lumber's expensive these days! We were really lucky in that we used free lumber from his family for the framing and floor... and old corrugated tin roofing that they had sitting around. The door, which we bought from the recycling center at the dump, was $25. Another $10 for a doorknob/key/lock set. We probably spent $150 (or more, I was too bummed to add it up) on joist hangers, screws, nails, etc. So... sadly, these days, $1,000 doesn't go as far as it used to...
And yeah, 2 x 4s seem to be the roosts that most folks recommend for them to keep their little reptilian toes warm...
