2003 Sable Keyless Entry Remote
 

I am looking to purchase another four button keyless entry remote for my 2003 sable. Do I have to pay the high price that the dealer would charge or can I purchase one off of ebay or amazon for a much lower cost. I'm skeptical of the cheaper ones only in that I usually feel you get what you pay for, but if they would also work OK then why not? Anyone out there purchase a non-dealer remote and have good success with it? Any recommendations?
