I take it you're looking for a white wine? I agree that a Reisling would be a good choice. I like a good Chardonnay as well - it's a little crisper and a little less sweet, but still very good. Pinot Grigio is a good wine, just not one of my favorites - it would also be a good choice.
If you want a nice lighter red, think about a Pinor Noir or a Zinfindel (red, not white). the Zin is spicier and goes especially well with the dark meat. Both go well with turkey, and tend to be a little richer and heavier than a white wine.
I'd say go for a bottle that's between $8-$12. I know it's not that big of a difference, but with wine, you get what you pay for, to a point. The difference between a $6 bottle of wine and a $12 bottle of wine will be bigger than the difference between a $20 bottle and a $100 bottle, believe it or not.
I'd recommend a Californian wine from Sonoma or Alexander Valley - more consistantly good quality.
Okay - now the wine snob will crawl back into her wine cave...
