Here is a link to affordable Mustache Handle Bars. You will need to add brake levers and bar end shifters, not a big expense. http://www.nashbar.com/bikes/SubCategory_10053_10052_200388_-1_200276_200303
Handle Bars are easy to change with a couple of common hand tools and some dish soap. PM me if you want more details.
There is another option for alternating hand positions that is very inexpensive and can be added by your hubby, or even you. Clamp On Bar ends for flat bars.

Shimano 2200 Series. Found on the higher priced discount store bikes. Used to be called Shimano Tourney.
Shimano Sora. Lower end recreational components.
Shimano Tiagra. Recreational components.
Shimano 105. Good entry level components often used by enthusiasts and un-sponsored racers.
Shimano Ultegra. Really good quality, what most un-sponsored racers use.
