I see that there are basically two types of openers, screw drive and chain
drive.

Are there advantages of screw type openers over the chain drives?

I would probably have the installation done by someone else-HD or Lowes.

Thanks.

Why then replace it?????????????????
And if replaced where would the perfectly well operating one (only 17
years old!) go; the landfill?
