not exactly beautiful, but cheap and functional. I have under $20 invested, and it's 2 foot wide by 18 inches deep and 2 foot tall.
The log hide cost more than the cage did. I obtained the glass at a rummage sale, it was a table top. $5 for the table, it had 2 identical panes of tempered glass, I threw away the frame.
The hinge was a spare I found, the light socket was about $4, the rest was spent on wood.
