Heavy duty desk?

I know this is slightly OT, but we all need somewhere to put our new
PC ... ;-)

....

I recently bought a new desk/workstation, but the lack of legroom is
driving me crazy (the low printer shelf seemed like a good idea at the
time!). So, time to try again.

The main issue is that it needs to be strong enough (and have space)
for a 22?.CRT monitor. That seems to rule out nearly everything I have
found so far, as they are all designed with TFTs in mind. It also has
to provide enough legroom for somebody who is 6' 3?.

A sliding keyboard shelf would be good, but apart from that I am not
too fussy.

Anybody have any suggestions or pointers?

Thanks
