CRT pros and cons
This is going to be a real oversimplification on a subject that you could write a book about.
CRT driven sets are generally said to have better black levels than Microdisplays (DLP, LCD,, etc) Thjey are also said to have a more film like appearance. Black levels are really important for movies. As you have already found out they also have a lower price point than their competitors.
There are three real downsides. One is their physical size and weight, a 65" set is big, deep, and heavy. Two, they also will require more alignment than the others. Three, They don't have a high light output and need a more light controlled viewing area.
So if you have the room, the ability to control ambient light and mostly like movies or productions like movies, TV ensemble pieces etc then a CRT will serve you very, very well.
Regarding the other technologies, yes they are newer, but they are very reliable and you shouldn't let their newness concern you. They work very well and in many normal household conditions have real advantages, such as brightness - you can watch them in a well light room and they will perform well and they take up much less space.
Complex subject, mainly decide on what you can afford, like to watch and where you'll put it.
