You can get smaller versions of the Naruto episodes at Hybrid-Anime.net, however they arn't translated by Aone/Anbu i'm afraid.

They're hosted via HTTP with a fairly good upload rate. It will certainly max your download rate if you're still using dial-up (Unless you mean DSL/ADSL, in which case it will be about 30 - 40KBps). The file sizes are small specifically for dialup users, but that means less quality of course. But the site hosts all of them as well. From 1 - 68. =P
