I've been studying ccna for a while now but I have only just come across these. I found two on lulu.com which were free. A lot of places seem to want money for them but looking at the quality of the material I may be tempted to buy some from amazon. I will have to go through them and check first though.
My first time on lulu. Need to register with name and email but then your straight in. Site looks pretty koshur(sp?)

Update: Had a look at this now and it does look like it will come in very handy. If you want practice on remote access / isdn/ etc, then this has over 100 pages of really detailed stuff. Just looking at it scared me (/gulp). Also 180 odd pages on routing labs and 40 odd pages on access lists.
