It all depends on how close the recources are to you, and how manageable you are with building materials. Its like the guy who wants to build a sick hydro setup but has never built a lego. You can make one very cheap very easily, but u need the know how, the time, and the materials, there are alot of threads in here on how to make them, so look em up, the hydro section were in is the best place to look. you really dont even need to get a guide, look in the cabinet section at what other people are using, the more creative and innovative your grow and time you put into it, the cheaper it will end up. ive built a pretyy serious cab before with 100 bucks in supplies from homedepot my own plan. worked awsome until the plants outgrew it.
