hi trey - i went onto ebay and bought for £1.99 ($???) instructions to make my own bater, seems to be working so far with humidity (bought a cheap one of ebay) and a nursery themometer that i "borrowed" out my daughters room (she has another one!) dont have a sponge in there but will do for the last week when i need humidity at 70-80%, hopefully at least one will hatch!!
Good luck
