That is a pretty good price imo. My buddy and I built 3 a few months ago and are finishing another 3 at the moment. The melamine, other wood (for building the frame for the door tracks) and sealer alone was about 150.00. That does not include the glass, tracks or lighting and that was just for 3. By the time it's all said and done I will probably have 1300.00 in the 6 cages. Mine are 12" tall x 49" long x 20" deep.
300.00 for material
200.00 for tracks, locks and full spectrum led lighting
650.00 for 6 rhp's, a thermostat and hides
70.00 for the shelving that the cages sit on
100 for the glass.
Looking back I could have done it cheaper buying pre-made but I needed specific dimensions.
