The Monitor is Dying

Hubs' monitor is slowly dying.  His CPU, printer and scanner are still working fine except for his monitor.  He is still using the old, bulky tv tube type monitor.  He didn't want to buy a new one then because he said it was still working.  And as long as he can use it, he says he won't buy.  But now he's seeing signs that it's going to rest soon so my daughter already started looking for  computer monitors.  I told her to order already as soon as she finds one, who knows how long the old monitor would last?
