I think you are looking for something that does not exist. IMO all you can hope for is 
a best fit
for the majority of tasks and a good interface to the other tools you need to get the 
job done.

I would not IMO say that any of the 3 are a complete solution for all aspects of the 
design cycle.

You are spreading across quite an expanse of $$$$$$ here, in fact for 20 seats, it is 
a petty major
gap if you are going to enable full seats for everyone.

I do not think you need any advice on Protel if you already use it. 
For multi user environments I am having serious trouble getting DXP2004 integrated 
within our
internal QA system and ISO without bogging everyone down with un-needed caveats and 
gotcha notices
that need to interfere with a natural flow, something as simple as Save or Save as can 
produce quite
different things at project tree level. 
This overhead is purely a result of the current way in which files are handled within 
a project and
the risk to design integrity through improper following of critical procedures and no 
redundancy for
the integration of remedial loops to make corrective actions (project rebuild). I have 
preparing some idea of mine on this but its not ready yet, perhaps I need to get 
moving before 2005
is released :-) 

But I would give your Mentor rep a bit of a commitment test up front as you will be 
paying major $$$
each year for as long as you own the tools, ask them to come in to your site, and 
tools based on your needs and specifically ask about training. 
They can tailor a license package for you so you do not need full suites on everyone's 
desk at same
time. For 20 seats of any combination that should be worth their while. If they will 
not do this
much for you, well, Cadence is worth a call too......

I only use Protel and Pads here, but I work with colleagues in Spain who have nearly 
70 people in
R&D and the whole dept use Mentor productions from end-end. However they do have a 
warning, they do
not speak highly of Mentor support, they prefer to invest in Mentor training for their 
engineers and
then handle product training and support in house. You can draw from that what you 

Sorry for the ramblings....
