There is a tin/bismuth alternative I found on rotometal and amazon, Tombob makes non-lead RB but are expensive.

for violating CA ban I found this on the Bill/law write up on the legislature page:

"...A person who violates any provision of this section is guilty of an infraction punishable by a fine of five hundred dollars ($500). A second or subsequent offense shall be punishable by a fine of not less than one thousand dollars ($1,000) or more than five thousand dollars ($5,000)..."
