building an incubator

[matt_winter]

hey

i dont think my leopard geckos are quite ready to be laying eggs, but when the time comes i want to be prepared. I have heard to use water and a fish tnak heater and place the container on bricks. What do you guys think of this idea, or what do you guys think is a better way of making it.

(if possible could you include pictures of what it should look like)

keep in mind a low cost for all of this

thanks
matt
