Don't put any money on Cisco 7500s; they cost more for every performance/price figure you might consider.
I don't know about Passport 15000, but Nortel Versalar 15000 was a pretty good router, basically an ASIC implementation of the Nortel/Bay/Wellfleet BLN/BCN boxes. As it vanished from Nortel site, may be it has been merged into Passport or died because of Juniper agreement; BLN/BCN/Versalar L3 features were very good, including a BGP implementation that outperformed Cisco's for many years.
If you need IPX, consider Cisco OSR (Cat 6K+FlexWAN cards) or Nortel's options; IP only, jump to Juniper M5/M10 without thinking twice.
