Bill, are there any "high-end gourmet stores" in your area? Some stores will have bottles to sample if you ask for a taste. If not, but the staff is well trained, they will be able to direct you to an oil that has the qualities you are looking for.

Generally, oils from the south of France are fruitier and don't have a burning or bitter after taste.

For Italian, look for a brand called Sagra. Italian delis here always have it stocked, but I don't know what it's like in your neck of the woods.
