I don't own a rack yet, but saw Cserpents at the last repticon I went to. The owner was very informative and professional and I liked how stable his racks were. I know that he will do custom work as well (multiple tub sizes on different levels, heat tape line splitting to run different temps in different rack sections ,etc.). He will also build racks to fit vision tubs. I will be purchasing a rack this year and it will be from him. If nothing else, his racks come assembled, which is a big bonus for me.
