Personally, i feed F/T because 1. all my snakes will eat F/T 90% of the time and 2. it is SUPER convenient for me so i really lucked out.
I get all my feeders from a local supplier and have a chest freezer (5 cubic feet freezer) dedicated to rodents, but sometimes i store regular food stuffs in it as well (lol i was SO confused when i pulled out a bag of chicken breasts and went omg what happened to these rats!?, my BF had put some chicken in there and forgot to tell me, whew).
I get great quality feeders and save shipping because i have a few local shows around me here or when i was in NY there were a few specialty exotics pet stores around me that had a ton of frozen stock. Since i buy in bulk i usually get a nice discount anyway.
Feeding live is a pain for me because my cats get SUPER predatory and i really dont have any room for mice where they wont be harassed constantly by the cats and thats not really fair, but i have fed live on a few occasions before and would again if i had to.
