We purchased our 12" 6 quart pre-seasoned Lodge Dutch Oven from Bass Pro Shop for $60.00.. which was the cheapest price we had found.
My DH has several cast iron skillets that he purchased a couple of years ago, unseasoned. When he first told me about the seasoning process and about not using soap when cleaning them after cooking.. I thought he was crazy. However, he has them seasoned just the way he likes them now.. and the no soap cleaning actually works.
Seasoning is an easy process.
Lodge has a great explanation of Seasoning and Care of your Dutch Oven which can be found at..
