I use to have the same mindset as well, but then one of my snakes got a nasty bite from a rodent (I was watching it, I just couldn't stop it in time) after that feeding day was nerve racking and eventually I just decided that the benefits (if any) of feeding live were outweighed by the safety factor of frozen.
I can understand your freezer problem, but there may be another option. Most of the local reptile shops I've been to that sell rodents will humanly kill the rodents for you. I did this for awhile and it worked out great.
