My girlfriend wants me to take her hunting...

Sooooo.. I'm looking for a shotgun. She can't use mine because they are too big for her, so I have to find her a youth model. I was looking at something inexpensive just because I don't know how much she will actually use it or want to shoot.
I came across the Mossberg maverick 88 on Fleet Farm's website and just curious if anyone has any thoughts or opinions on it. It's cheap, $199.99 cheap.
I have always been partial to the 870's... maybe I should just pay the extra 100 bucks and buy an 870?
