I would think 2500 series routers, ios 12+ and 1900 series switch's ios9 will work
Bear in mind that CCNP is now based around the 2950 switch! these can be expensive but I picked up a 12 port one of ebay for £100 ($170) some of the commands etc arent compatible with the 19XX series.
Really, you found one for $170? Is it banged up or something?
