I've used some of those Dia Compe levers on a single bike, and I would not recommend them - the hoods are way too narrow and hard, not comfortable at all; the Cane Creeks are way better. Also see if you have any friends who have any crash-damaged integrated shift/brake levers hanging around - they might give them to you for free. It should be possible to remove most of the internals and levers from most models.
