Another thing besides weight that you have to keep in mind is their size. Something like a 36" CRT is going to be a tight squeeze where your house, vehicle, and where you intend to operate it is concerned.

Before considering one that size, it's best to take some measurements first. I couldn't even fit a Trinitron about that size in my Impala, and it's a full size passenger sedan. I luckily thought about that a few minutes before leaving to pick it up and saved myself and the seller the hassle.
