I have an AT950. The A920 is now, I think, obsolete, although there'll be plenty of examples on eBay.
They both fit the 900 and KM series machines. The original 920s and the new 950s both have metal innards, including the screw mechanism that pushes the meat through the grinding plates.
But for a while, Kenwood produced A920s with a plastic screw, which many people said wasn't up to the job.
You can buy the sausage tubes for the A920 easily enough from the usual spares suppliers or on eBay.
