I think they have some nerve jerking you around about the mask as well as the machine. Prices online that I've seen are the same for both the regular and the For Her Quattro, so they are just suiting themselves at the expense of their customers.
I, for one, appreciate that you would like the pink. I was very depressed about having to go on APAP until I saw the ResMed machines and mask options, and when I saw the pink I was actually excited about it. It just made a world of difference mentally - and that's where it's at when it comes to APAP. A lifelong life altering experience with plenty of adjustments to lifestyle and one's self image means the user needs all the help s/he can get with comfort and, yes, style. The pink autosets don't cost any more than the gray autoset, either. If you want a red washing machine, you have to pay a premium, and everyone is only too eager to sell you one. Why should anyone want to deny your choice of something that's going to spend at least 5 years sitting right in your bedroom staring you in the face, and not buried in the basement or laundry room? /rant
