I picked up the 'stereo' box of UK releases a few years ago, and that's more than enough for me. I grew up listening to the American versions ("Rubber Soul" might have been my first record), but with one exception I'm not desperate to hear those versions again.
I DO want to get the US version of "Help." The incidental music was an integral part of the album for me, and I probably haven't heard that stuff in about 40 years.
I have a friend who's a Beatles collector, so anything I need to know or hear I can get from him. He buys EVERYthing!
