During my quest to find a useful tool to study with, while waiting for the Labs here, I found this website www.tncpods.com/publiccisco1.php . Its not a real set of cisco routers like what you guys are trying to put together, but the trainers have 3 routers connected serially and via Frame Relay.
R2 (S1/1) --- (S1/1) R1 (S1/2) --- R3 (S1/1)
R1, R2, R3 --- (S1/0) Frame Relay connection on each router.
I was able to use it to study for my CCNA (parts of it anyway) and all of the BSCI. Best of all its free.
Give it a try.
