Lots of experts here to help you (I'm not one of them- we are still in the beginning stages of our build)
Please post the details of your build: size, type of sanitation, equipment, plaster or pebble, etc. and you will get great input on the best options for you and what not to waste money on. Oh, we can also HELP you spend your $$,too!
