When I was at the store last weekend there were squeaky toys made out of fire hose material...I really don't remember the brand but they seemed very durable.
I have one of these, called katie's bumpers. I got mine at a local pet store but have seen them online at twobostons.com.


also, on the note of pet toys, if you guys have never been to petedge.com, you gotta check it out! they have CHEAP CHEAP CHEAP stuff!! I just bought a bunch of stuffies for under a dollar because alki destroys them so quickly! lol also got some kong toys and rawhides and a bunch of random crap for super cheap.
