Cisco has a list of approved third-party memory vendors that you can use. In speaking with a technician about upgrading some routers, he gave me vendor part numbers and everything. I'm quite sure Kingston was on the list as well. One thing I did run into lately was early early early revisions of the 2500 series not taking Kingston memory due to some kind of requirement for an intel chip ID.

Mike,
Thanks. I do have a 7200 which I am building for this. Your input was helpful. I did find that Kingston sells Cisco memory at 40% of what Cisco asks for it. Does anyone else have cheap sources ? Regular memory does seem to work but I can't get an answer from Cisco what is "special" about their memory other than the price.
