I have an Ideal one that I fished out of the dumpster at the supply house. Somebody didn't like it. Had a kink at the end so I just cut a couple of feet off. This is the plastic flexible one and it goes through pipe great. Don't expect to fish walls and ceilings with it though.

For ceilings especially I have the fiberglass rods. They do shed splinters after awhile. I'll have to try the lacquer treatment, else wear gloves.
