Great, thanks! From the reading I did so far I was leaning toward a Cabernet Sauvignon and a Chardonnay, but I'll look into the Sauvignon Blancs.

Thanks for the tip Maria. I guess I didn't chose good search terms before because I did do a quick search before posting and only found a few threads, but doing a few different searches now I do see more results. I also wasn't sure how frequently these suggestions would chance-- ie. a wine that's good one year is no longer recommended the next. But I will take a look at some of the more recent threads.

Hi folks,
My wedding is later this year in Maryland and I'm trying to decide on what wines to serve, as we'll be providing it ourselves (ie. caterer can't help me because they don't provide alcohol). My fiance and I are big beer drinkers and really don't drink wine much at all, but quite a few of our guests are big wine drinkers and we want to keep them happy. We'll be serving a buffet dinner that includes chicken marsala, prime rib, a vegetarian pesto tortellini dish, and a tossed salad. The reception will run from 6-10pm. I assume we want one red and one white and we want to stay around $10/bottle. I've gone through lists of cheap wines but I get totally overwhelmed. Suggestions?
Thanks in advance for any help!
