Try to focus on the US Capitol releases, the black label with rainbow colors around it. Mono pressings are better sounding in many people's opinion. They are usually going to cost more.
If you just want Beatles on vinyl, the other American Capitol pressings, green label, purple label, and the latest (put out a few years back) black/rainbow labels are OK.
You can get Get Goldmine's record pricing book if you want to get serious: http://www.amazon.com/Goldmine-Record-Albums-Guide-Album/dp/0873417801
It will help you identify all the different pressings and values.
Have Fun!
