RH doesn't have to be about spreadsheets or making it something you have to worry about all day everyday. We often times make the process more difficult than it needs to be and paying that much for a device is a bit over the top to me...there are great hygros that work perfectly and one doesn't need to devote so much time to the effort of keeping a certain percentage. I know that some have an OCD thing going...most of us go through it at one point or more but once you trust your equipment and it proves that you are in a good range then you can relax and just enjoy the hobby .
