Drake Toilets

I was just on the TOTO website looking for a new toilet to replace the Mansfield that I have now and was looking at the Drake toilets and there was at least 12 different Drakes listed can you tell me what the different is on them.

thank you,

William

The three different models are:
CST743S, Regular bowl
CST744S, Elongated bowl
CST744SL, Elongated ADA height bowl
adding the "G" makes it CEFIONTECT, this only comes in the CST744SG
adding the "B" means the tank lid bolts down, handy in commercial bathrooms.
adding the "D" is for "insulated tank"
"DB" insulated tank with bolt-down lid.
