2003 SAAB 9-3 repair Question Automatic Radio Antenna Replac

My electronic radio antenna's motor needs to be replaced at an estimated cost of $ 600.00. (The mast does not need replacement.)
I'd replace the antenna motor if I had any confidence at all that I wouldn't have to replace it again, but I do not.
I'm looking for a small, rubberized replacement antenna that will be effective in functionally picking-up FM stations.
Two questions:
1) Can you recommend a rubberized replacement antenna?
2) Can you recommend an installer in the Greater Ft. Lauderdale, FL area?
Thanks for your help.
