So, the opener I have now is an older Craftsmen (don't remember when I put it in) chain drive opener that still works but it seems like over the last 3 months the remotes in the cars are getting weak (8 out of 10 times, I almost need to be in the driveway for them to open the door) and yes I have replaced the battery on both of them. With that being said I am in the hunt for a new opener. What brand do you think is the best and would you get a chain or belt drive on the new one? Thanks.
