Semen tanks brands... Pros/cons if each brand???

I’m looking into the possibility of keeping a semen tank at home and am wondering what people know about these brands.

I love my mve tank. I’ve had it for 6 years now. I got the best price from semen tanks.com. I don’t remember the model number but it holds the charge for 4 months.

I like the MVE tanks too and have also found the best prices at sementanks.com

I also have an MVE (Millenium 2000 XC 20). I am very happy with it.
