If you want to save money to get started the best thing to do is build your own..you can buy 28gt,and 41gt tubs at wall mart for cheap. After you get going into the hobby I’d suggest buying a freedom breeder rack..that’s my next goal. I built my racks and use tubs from Walmart and everything works great. Once I get some money together I’ll invest in a freedom breeder rack. But to start out I’d suggest building your own then you can make it as high as you want and wide as you want.
