Just to help you out a little. There is no such thing as a 'water-proof' M/C jacket, sure, Goretex, Outlast etc, all do a very good job of keeping you dry, but given the right environment, they will all get soaked over time. The liner is the last line of defence, as that is what it ultimately going to keep your skin from getting wet and misery sets in.
Trawler fishermen's oilskins are the only thing that is water proof. Remember, the jacket has to be able to also dry out whilst riding, so the fibers have to let air pass through but not water, though to do. That's why manufacturers recommend a very specific cleaning schedule and regime.
I personally think the high-end gear is not any better than the lower priced Goretex gear, but the zippers, seams, liners and protection will be, and that's what you are paying for the most.
