Are easy-rekey locks reliable?
I think you answered your own question... "I don't especially care about being able to rekey the lock myself".  If you don't want this feature, don't pay for it.  Pick up a good sturdy lock from a trusted manufacturer, that has the features you want.

If you want to use the same key for all the doors in your house, you may be better off buying new locks for all the doors.  Most hardware stores carry sets of locks; where you'll get 2 knobs and 2 dead bolts that all use the same key, so you can set up 2 doors to use the same key. You may be able to get sets for more than 2 doors, but they might prove more difficult to find.
