Hey there Merlin,
Many new wine drinkers will find Merlot's and Zinfandels very accessible for there palates, and there are some good ones in your price range. Your probably going to like wines that are more fruit forward, not necessarily sweet, so when you talk to people at wine stores that'll help you describe something to look for.
As far as producers go, check out some of the larger producers to find good wines in your price range, Beaulieu Vineyards, Beringer, Buena Vista, Chateau St. Jean, etc.. . For Zinfandels I would recommend Rosenblum, Brazin, Cline, Clos LaChance and Michael David Phillips Seven Deadly Zin. All are good producers and offer some reasonably priced wines.
We attended a large Zinfandel tasting last weekend in San Francisco and had some outstanding wines, most that I liked are smaller producers and hard to source outside of CA. If your interested, I can give you some of those names as well.
Good luck and welcome to the world of wine!
