20 years ago i installed a Fujitsu 42" in a clients bedroom. 10 years ago he upgraded it and was happy for me to take it. $120 for a floor stand it could mount to with a couple of shelves underneath from ebay and my Mum is still happily using it today.
It will probably outlive the Samsung 9 series i recently bought.
