Hello Gene,
The UC520 is still too expensive for a lab router but you may take a peek at the SR520 as you may find a deal if you keep your eyes open! Would be a nice addition to a Voice lab I am told!
UC520 and SR520 Router setup! Has a nice example as the SR520 has integrated 4 port switch!
SR520 on eBay: (Gotta love the seller's username.. Kind of has the subliminal message thing going on! LoL)
I would point out one thing Gene.. They list three different types of phones in the above link (for no reason actually) but I have been told on several occasions that you SHOULD mix it up and use a few different models! Makes since actually so you can become familiar with the advantages/disadvantages of different models and not have to spend the MAX price times 3! LoL
OK.. That said the amount of features (Voice Related) available to the 1760 over other routers is significant! Here is a list of features that the 1760 w/ Advanced Enterprise Services c1700-adventerprisek9-mz.124-15.T8.bin has over the maxed out SR520 w/ sr520-advipservicesk9-mz.124-22.T.bin... This is why so many people opt to include the 1760 (Note that there is a plethora of features available on the newer SR520 but most are Security/QoS such as RADIUS/TACACS+, IGMP Snooping, CEF 6-to-4 tunneling, lots of IPv6, SPAN, Wireless with WPA and a Zone-Based Firewall! However, check out the 1760 advantages:

A lot of this stuff is Voice related and is why you will want a 1760 in your lab! (Plus you can not beat the price!)
I would research the possibility of this setup..
1760
2x 3550 (At least one EMI but I have read that you can upgrade an SMI to EMI)
SR520
7940G (IP Phone)
7960G (IP Phone)
7970G (IP Phone)
I would also post the setup that you are considering in CLN and place it in front of as much criticism as possible prior to purchasing!
Also, I would print out the blueprints for the various CCVP exams and start comparing required features.. Some should overlap and most should be covered by the 1760 and 3550's! I am certain that the above setup with the appropriate cards would cover everything but again I would post to CLN CCVP as well! Maybe even throw up a short question on DSLReports in the appropriate section! Hope this helps!
