My personal olive oil of choice, for what it's worth, is Frantoia. At 30-something bucks a pop for a liter bottle, it ain't cheap though. I usually pull the stuff out for dinner parties and special occasions. It's a very hearty, yet amazingly smooth oil that makes a very noticeable difference in my cooking when I use it. It is of course fantastic on it's own with bread and a touch of sea salt or balsamic vinegar.
You can usually find bottles of Frantoia at the Sam's Wine located off Clyborn, or at Fox & Obel.
Lately I've been purchasing my other go-to olive oils at Graziano's. Salvati, a fantastic unfiltered olive oil Graziano's carries, has become my everyday olive oil of choice, and is a relative steal at around $11 a liter. They also carry a high end olive oil from Sonoma Farms (in California) that I thoroughly enjoyed, although I can't recall the price point they offered. It's worth checking out, though, and Sonoma Farms' website lists a 9.8 ounce bottle from around $10. I did find it's way too delicate to cook with, however, as it has a very low smoke point. I usually keep it around for salads and bread dipping. Graziano's has been discussed elsewhere in depth on this board:

http://www.sonomafarm.com/pro_detail.php?id=59As for Old Town Oil, I have to agree with Darren72. I was really unimpressed with this place. All their oils and vinegars tasted watered-down and thin to me, for lack of a better term. What really threw me, though, was a sample I tried of what they claimed was a either a 12 or 16 year old balsamic (I can't precisely recall the year they advertised). It was thin, runny and didn't have any of the depth of flavor or texture normally associated with a good balsamic of that age. I was tempted to call shenanigans on them, but ultimately thought better of it and just walked out.
Hope that helps.
