I got mine at Home Depot because my local store had them in stock.

I love everything about it! It's classy and modern-looking. I love the smooth "skirt" design with no "pipe" outline or external bolt covers etc. to gather dust. The dual flush/vortex works great, and it's sweet to have a soft-close lid (it's mesmerizing to watch it sloooowly close). Best of all, it actually takes up LESS space than my old compact round-seat toilet--both length and width! That's important since my bathroom is tiny, with less than 10" clearance to the cabinet on one side and tub on the other. My plumber had no problem at all installing it--correspondence with customer service at Swiss Madison confirmed they listened to customers, and have improved the design to make it easier to install.

And it was cheaper than the standard Kohler brand (Lowes, Home Depot) that my plumber had recommended--now he says he'll be recommending this one as an option to his clients.
