Chinchilla sand is the only safe one I think. There are big debates in various places over the different contents of different kinds of sand and some people say no sand is safe!
However many people on here have used this one for a long time with no issues. I find it doesn't work out expensive if you get 2 or 3 at once and only pay one lot of postage each time. With a sandbath also, you don't need to replace the whole lot each time, but can scoop out any wet areas and just replace that bit. Or scoop out any poops if they get too many.
I just use it in a litter tray for our Syrian and one lasts a good few months. If it's for a dwarf hammy you'll need an actual sand bath but they may use it as a toilet as well.
