My house has a pretty standard 68"Wx80"H entry door unit - 36" foam-core door and 2 sidelights.

I'd like to replace this with something nicer. I have a set of Marvin patio doors, and another (unknown brand) patio door with 3-point locking - both have a heft and premium feel that is clearly lacking in the lightweight front door.

So my goals are an aesthetic upgrade, an upgrade to a more "premium" feel, an upgrade in air-tightness, and an upgrade in security (replacing the cheap Schlage lock with something better).

I'm leaning toward something painted, as I don't think wood will look good with the rest of the front facade.

I'm surprised at how obscenely expensive entry door units appear to be, which has led me to think of building my own. I have built a single entry door, before, and am comfortable doing it, but never built one with a jam.

Any entry door wisdom? Things you like, wish you did different, etc?
