Yeah Maryanne's advice is pretty spot on.
The Palm Luna (womens ba) is essesntially the same as the Extreme which i have, but is designed in terms of fit and and shape for the female shape. The amp is also the same but an over the head job. Pros: Really great bouyancy aid, very well thought out. Excellent freedom of movent loads of room for gear. Cons: Price, its a top end ba and priced as such. Bulky up front, some people find it too big in the front, i havent.
The Axis is super too. I had this ba for years really happy. Pros: Best value ba on the market in my view. Its unrestrictive has a nice big pocket and its not too dear. Cons: Its made from one flat slab of foam so it doesnt hug your body the way a curved block does. Some girls i know didnt find it comfy, but maryanne loves it, try before you buy. The zips seems to rust, but i think palm have sorted this?
The Astral green jacket is also very popular. Its an unrestrictive top-end ba priced as such. I dont have one but plenty of people in the club do.

Any of these are pretty good i dont think youd go too wrong but try before you buy. and remember youll get 10% off all the irish retailers.
