I think the Panasonic BH-941P is an excellent product - would thoroughly recommend. I believe it may now have been discontinued though which is a shame. The last set of batteries only made 4 - 5 batches of ice cream - these cost around £5.70 so a significant cost factor. I think the claim is that they should last for 30 or so batches so a big shortfall. My mother-in-law put the battery / motor housing in washing up water and killed it - I had to get a replacement.
