Newbie needs a board

I just started wakeboarding and now I'm an addict! I am seeking out some information on a good board for a beginner that will still give me some room for advancement.

From reading previous posts, it sounds like there isn't any difference between men and women's boards except color. Is that true?

What size would I need? I am 5'5" and weigh about 135.

I am leaning toward either a hyperlite or a liquid force board. Any thoughts on who puts out a better board? Any suggestions on models?

Any help would be greatly appreciated!
