[OT] What to use(was Lead Rot)

Hi all,
 After having been using lead for 5 years it is time to switch to
something a little less toxic for casting purposes.
 What does the group suggest as a good alternative ?
I am looking for ease of use and cost does matter. I used to get my lead
for $.25 a pound and used it in 2-part RTV molds.

Thanks,
Kirk
