Which one to buy and where to buy from.

 

You dont need an expensive named catch can. I bought mine from ebay for about £40. Get one with a 1/2 inch or larger inlets. Two or more inlets-if possible, a drain plug on the bottom and a indicator to show how full its getting.

Mount the catch can as high a possible and centrally in the engine bay. This will stop oil being slosh up and into the can if being used on track.
