It stings the nostrils
I wanted something nice looking so i went with one of these. They also do custom sizes. The stock one is around 9.5 gallons.

That is very nice, but I can't buy from them. I tried to order a custom sump from them and after several weeks and three emails, they refused to do business with me, saying that I changed my mind to many times and bothered them too much.
