bike computer mount help needed

I need some help b/c I getting fustrated trying to make something work.  Here is the deal.  I use a profile design aerodrink bottle and have a cateye bike computer and I also have a Garmin 305.  There isn't enough room to mount either one on the stem and the aerodrink takes up all the room near the front of the aerobars. The only room left is almost where the tape starts on the aerobars. Are there any short folks out there that have some creative system to mount their bike computer?  Any help would be appreciated.
