They all seem to like wings on here but I (and a couple of other diving birds) love the Seaquest Diva LX. It fits women beautifully, is mostly a wing but has a jacket design. It has plenty lift and is very stable and comfortable in the water.

I also like APEKS regs but everyone to his own. They are very highly recommended by most of the divers I know.
I started off with cheap kit and replaced it all after about 18 months. Now I love my set up and would never wish to change it.
If you could try some different stuff out in a club pool before buying it might be helpful.
