I installed an American Standard Clean Cadet 3 last summer. It's ADA height, which Dave needed, and it really makes a difference. And it goes without saying that if men are going to be using it, you want an elongated bowl.
I shopped around quite a bit but I came back to the Clean Cadet 3 because of its smooth sided design and clean lines. I'd love to have a wall-mounted toilet but that's only going to happen with a complete gutting and remodel job, so the clean sided design is the next best thing.
One thing to consider is that you'll be better off if you have help when mounting this particular model onto the flange. Since you're not able to see the holes for the bolts to fit through as you lower the toilet onto the flange, you need a spotter. There are two large holes on each side of the skirt which provide access for tightening the toilet down, and as well as a side view when positioning the bowl portion onto the flange.
I'm generally pleased with the way this toilet performs even though it's a low flow model, and surface area of the water in the bowl is larger than most. The cost was around $230 at Lowe's (the only place I found that carried this model) and I think they've come down in price since.
My main complaint is that the "Ever Clean" surface isn't, and because of this treatment you can't use strong abrasive cleansers to clean the bowl, and certainly not a pumice stone, which I use once in a while on the other two toilets here because they develop lime deposits. The "Ever Clean" doesn't seem to allow lime deposits to form, but there is a faint ring that "scrubbing bubbles" types of cleaners along with a bowl brush can't quite get rid of.
I've attached a picture and linked to a demonstration video. Notice in the video that in almost all cases, it appears the flush lever is being held down until the bowl clears. My experience has been that for routine jobs, it's usually not necessary to hold the lever in order to clear the bowl.
