Given the recent discussions about mice, reptiles, and disease prevention, I thought I would post a link to the company that I buy exam gloves from. I buy these by the case, and wear them for just about everything, including cleaning cages and tanks. This company offers the best price on a case that I have found and the best variety of glove types and thicknesses, and the gloves are top quality, IMO. I have to order medical grade, but if you don't have a health care element in your tasks in which you need to wear gloves, then the prices are even cheaper.
