Yeah, really :p
Obviously it depends on the size
A 17 inch CRT doesn't take up a lot of space at all.
I think they're worth the space, I tried about 5 different LCDs but was never happy with how the Amiga looked on them. Often you forget how a CRT looked when you haven't used one for years, and you get surprised when you see them again just how nice they look for standard definition content.
Don't get me wrong, I use my modern systems on LCDs, but for 8/16-bit machines, they look so much more authentic and how I remember on a CRT. If I was going to use an LCD I may as well just use an emulator, as the display is one of the biggest parts of the "real hardware" experience.
