www.reptiledirect.com or www.bigappleherp.com maybe Petco or Petsmart. Usually most stores do not carry them, online may be your best bet, unless you have to time to shop around.
if there is a petco or really any pet store near you that carries zoo medthey should have the zoo med tongs, i know they come in a couple of different sizes i just go the ten inch ones and they are very sturdy they look justy like big tweezers. check the zoo med website.
