There are two types of chillers. One that is mechanical and one that uses ice or dry ice. Technically in my world a chiller is a mechanical device. If you are thinking of buying a refrigeration chiller make sure you have the power capacity from your generator or you have wasted your time and money.
For an ice bath style a large quality cooler, fittings, circ pump and hose and you are in business. The quick connect fittings are a small fortune, but worth the cost in the long run. As Rick pointed out having quality wheels and tires make maneuvering a chiller around is important. I made my chiller and also have a 15 gallon cooler that sits on top of the chiller. The more water capacity you have allows for quicker recovery on chilling the water back down.
