Shopping for Semen tank

[ruhtram]

I have roughly 20 head of cows and looking to purchase my own tank. I currently use my grandpas tank and would like the convenience of having my own. I probably have around 70-100 straws. I'm looking to grow my inventory and need some help deciding which tank would best suit me. Any advice would be great!

My advice is to get the big tank.  Only has to be filled twice a year.  Costs the same to fill a big tank as a small one.
