Stanwell and Savinelli are great pipes and available readily at many places for fairly reasonable prices.
Here is a link to the Savinelli natural pipes - these have no finishing stain to them and go $40 bones you can get one with a vulcanite stem or $44 for a lucite stem. Lucite is a more durable material will not oxidize like vulcanite will - vulcanite is a softer material on the teeth. There are many different styles to choose from at Pipes & Cigars. (vulcanite)

Here is a link to their listing of Corn Cob pipes - lots of them there.
Hope this helps.
Peace of the Lord be with you.
