My suggestion would be to examine the Toto Drake ADA. (CST 744 SL ADA) You do have to realize that ADA toilets do not come with round bowls, and this is a 2 piece, but unless there are overpowering reasons to go with a one piece round bowl, this would be an excellent choice. You can see these by clicking on "Toilet Reviews" at the top of this page, then click "Shopping" and finally "Toto". This will give you a rundown on all of the Toto models. Terry's prices are perhaps a tad less than you may have to pay, but they are seldom sold at MSRP. Another good choice would be the Toto Altramax ADA. It is a one piece, also elongated bowl only.
