I agree with everyone else, I have found some great deals at reptile expos for complete setups. I bought a complete setup, lights, plants, supps, spray bottle, & dripper for $115 with a small cage, and $125 with a large cage from amazing blue reptiles. At LLL you can purchase half glass, half screen large cage for $109. But if you build your screen cage you can save money, but then you have an initial investment of tools, supplies and risk making an error. I am going to build my outdoor cages, and an indoor cage just to try. I'll keep everyone updated on the cost and of course pics. Check out youtube for directions on building screen cages. The real cost is the customization of cages like jungle gyms, vines, plants, digital temp/humidity, misters, drainage, etc. It's addicting. Good luck, hope this helped.
