Upgrading memory in a cisco router?

[quackers]

Hi all,

Im looking at picking up a couple of routers to help with my ccna study, ideally 2500's of some sort. Now ive noticed after looking around a certain auction site that they dont seem to have a lot of memory and are running an older iso.

Now my question is this, how hard is it to upgrade the memory on the routers? Anyone done this before?

Cheers mate, it looks easy enough.
