Tripod - 20 MB storage, 2 pop-ups
Angelfire - 20 MB of Storage, 1 pop-up, occasionally 2 pop-ups

If you don't like these, then i giess you'll have to look a bit harder, but most of the other servers that provide like 50 MBs or something,
are not stable and should not be used, if you want something more spacious, and advanced, then buy a domain, and a some server space, and you'll have
as much as you need.
