Thanks Jason. I had no clue what an automatic bottom seal was until my pro friend told me about them. The combined cost of the seal and sill is about twice that of an adjustable sill, and it takes a lot more effort to install the seal than other options, but it gives a nice clean look and eliminates the trip hazard of many adjustable sills. I'll probably use the same approach for my own new front door because I have a cement threshold, too.
The lockset/door knob was chosen by the home owner. I take no credit or blame for it. The house is some sort of Spanish style, inside and out, but the owner is an Arts and Crafts fan. Only way I can explain the lockset.
