I get annoyed when I see snakes being rehomed on craigslist with an excuse of "I don't have time to take care of it"... If you're running your heat source on a thermostat (which you really need to do anyway to make sure it doesn't get too hot) you shouldn't have to adjust things much at all. The only real "time" involved is a quick spot check of the enclosure every day to look for urates or poo, and to change the water every couple days. Then as mentioned above, feeding... If you feed live, you have to make a run to the pet store once a week to pick up feeders, then bring them home, drop them in and watch until the snake strikes. If you're feeding frozen, it's a matter of pulling the dead rodent out of your freezer in the morning and setting it out to thaw. In the evening when you're ready to feed, warm it up with a hairdryer and offer (you may have to do the zombie rat dance, which might take an extra minute of time).
You don't HAVE to handle a bp at all. They don't "like" being handled, they merely tolerate it. The handling is for OUR benefit as keepers.
