I read your whole post twice 'cause I thought that you might have a problem ( I look for folkes with worse luck than mine so that i can feel good about Me) and then re-read it.
I fail to see any form of a problem here . Come on, do the right thing, Man up and give the girl the gear. If she really wants it she'll get it any way , so if you hand it over before she asks it looks like its all your idea. You get the credit and she's all flush with "good will". Talk to some of your "older" married buddies about "Good will" and the benifits thereof.
Another thought.
I hear that the new "Helios" are too cool.(flygoddess can tell you)
Mention it to your girl around Christmas time(subliminal message{good will})
Remember these two critical words:
Good Will.
Cheers,
