Western planes require plenty of setup and tuning when purchased new unless you spend over $100 to get one of the better brands.
Before committing too much money you might want to get a cheap, used #4 Stanley Bailey so you can see how they function and mess around with tuning it up. It would be a shame to spend $150 on a nice Lie Nielsen plane only to find that you prefer Japanese tools.
Western plane blades aren't any easier to sharpen than the Japanese types so you'll need to learn sharpening skills one way or the other.
Also, Japanese planes are designed to be pulled so their ergonomics are geared towards that.
