X16 Xblue may be ready to rise again on your radar. You can run up to 4 phones on a single shared pair and your Mom can still keep her cordless phone wired ahead of the system. When she uses it, the line lamp will show it too! Those X16 phone sets might grow on you and and the navigation button is similar to cell phones. As you are finding out, identifying the features you need rules out most of the cheap Ebay systems. That is why they are so cheap. If you were local, I would even just give you one of my old retired systems to play with. I don't even waste my time posting those types on Ebay that flood Ebay.
