No need to pay dealer price or LMC price; typically you can find them at your local auto parts for about $15-$20 depending on what store you go to. Almost all of them stock the handles, though you may need to go to more than one store to get the color you need. Or, get whatever they have available, and pop the metal handle portion out and install it to your original base. The base generally never breaks (unless someone breaks it removing it) just the handle portion. Takes about 1 minute to swap the part over.
They're all pieces of crap, including the original factory ones, so I wouldn't fear buying them from wherever. But again, they're as close as your local auto parts store.
Be sure to inspect your door hinge pins/bushings for wear (open the door a little bit then grab the rear of it, lift up and down to check for slack) as the beginnings of wear there is the usual main cause of breaking your interior handle, as the door gets harder to open and close.
