I decided on this tank because of the sight window for fluid level indication and the price. When I received the tank i was futher suprised to find out how sturdy and well made the tank is. Its a good thick gauge of aluminum and looks sharp. I decided to go with the silver color instead of the blue and it looks fantastic. If your thinking about other tanks don't do it. This tank is the best value on the market and the guys at accurate are great people who put out good products. If i had 1 gripe id say they need to come out with a matching cap for this unit
