Recommendations for 4th monitor options

IN the monitor escalation wars around my office, some guys have hit 8 or more, setting monitors on your CPU or cardboard boxes have been popular. Also one guy has built a series of shelves from wood to hold his monitors all in the positions he wants.

"Dell sells a few of two tier monitor stands like this one.

The monitor stand that I have also allows for a second tier extension"

"Not sure about the productivity part...

I have three, but I haven't found the head movement an issue over the last few years.
Maybe I'm different?

the left is mainly browser(s),
the middle are text editing (xterms or similar), and
the right is all communications (skype,IRC,gaim,email,VoIP).

I end up running text windows on all three because of remote multi-host activity I do.
Add spreadsheet planning and documentation and I'm not convinced a 4th wouldn't help.

But wouldn't really know until I tried (the 17"" glass CRT I tried was just unbearable).

Word of warning to those of us with multiple monitors however...
when you travel, can you actuallly work off your laptop anymore?

It's tough."

Try Allcam stands. Very cheap. Around £100 in the UK for a 4 monitor setup.
