This sight is very informative. I am interested in purchasing a Drake. However, on the TOTO website, there are several types: Bolt down lid, insulated tank and both combinations. Are the bolt down lid and insulated tank suggested?

Also, is the Drake very quiet, as we have a small place and the bathroom is next to the kitchen and bedroom.

Finally, is the Drake II better than the original Drake,

Thanks in advance for your assistance.
