I own the suro 20. I have had this for a few years and until I got it I had a bad hatch rate for Serama's . Seramas are very difficult to hatch...having said that I chose the suro 20 as I had total control of all setting. So far I have had many hatchs. BUT now I need a new mositure waffer and new tubing. Was hoping that maybe you would have some idea where I could find these items.
