Considering that she is brand spanking new to diving (I assume if she just enrolled for her OW cert) I would suggest Mares Avanti Plana. They are (if I recall...) significantly cheaper than the Mares Avanti Quattros (if I'm naming it wrong, forgive me- I don't have a pair to check the name against!). The Planas have 2 channels instead of 4 which the Quattros have (again, forgive me if my memory is wrong). At this stage, she doesn't need the ultra best propulsion she can get... it ain't going to matter until she gets "good."
I got certified in '02 and bought the Planas. I wear them now and unless I drop one off the deep end of the quarry I have no plans to replace them.
If I recall correctly, they were about $70 as compared to $140 for the Quattros.
And the mask... pink. Definitely...
The first mask I bought I did try on. I bought it because it was one that had a nose purge and I liked the way it looked better than "regular" masks. Alas, I bought it at a Sport Chalet who was more interested in selling me something than making sure I bought the right thing. I didn't try it with a regulator in my mouth and didn't find out until I did my OW dives that I couldn't get my fingers to my nose to equalize. The mask fit but this whole "equalizing" thing didn't work so well. I would still use the mask as a backup if I needed to, but I ended up buying another mask that both FIT and was PRACTICAL.
I don't know what prices are where you are but around here (okay, okay, four years ago) they were $50- $60 across the board no matter what mask you wanted(and it's a small board at a small dive shop).
I did buy the pink one, though. If all else is equal, a little color can be fun!
You should see my snorkel...
