Physical gold. Buy from a dealer over the internet and pay only for shipping. Usually for gold the total price is $10 over spot for one ounce. Buy in 50 to 100 ounce lots to get the best price.
Silver should be a better deal than gold since the ratio is getting wide, >50 to 1. People speculate that the ratio should be getting back to 30:1 or lower. I would buy silver if you have mid 3 figures to invest. Gold is should be for mid 5 figures.
