Not sure how BIFL it will turn out to be, but we got a Little Snowie Max a few years ago. You can just pour in ice cubes and it does a decent job.

I love my Thinsulate-lined L.L. Bean boots (blue uppers and blue lowers). I've been wearing them for 8 Michigan winters and they've never failed me, even in -25 degree F polar vortex weather. Customer service was awesome when it took a couple of tries to get the right fit.
