I suppose the answer lies in what it was you may be looking for along
the way... I have taken a look at some of the practice study test that
they have for CCNP and CCIE, and they bring a valuable service!
In addition, the multitude of whitepapers are really quite good at going
through the different types of technologies and what they mean, what
they do and how to work them. Most of the stuff is Cisco-oriented (just
quantity of cisco folks around I guess!) but that shouldn't affect what
type of information there is.
Whether you are working on Nortel equipment, Juniper equipment, Cisco
equipment or other stuff, most of the basic technologies are still the
same.
If you are looking for a quick, easy and cheap way to get from CCNA to
passing the CCIE lab, you are right, that was likely a waste of your
money. However if you are looking to expand your horizons, actually
learn something about the technologies you are configuring and just
having a nice, quick repository for information, then it is well
worthwhile!
While I have done some technical editing for them in the past, I am not
in any other way associated with CertificationZone. So take my opinions
as you may. But I continue to find them to be a valuable and accurate
resource for information within the CCIE Realm.

don't sign up for certificationzone. you will waist
your money. you can read all of this topic from cco. i
used to be a member of the zone so i know. most of
writters of this site are nortel guys some cisco guys,
so you will not get much helpful info from this site.
