Look for these style pipes. Wellington, Yello Bole, Chesterfield, Well /System style pipes on ebay. Some of these are huge and were made in large numbers. You can probably find one in your price range. Just look for listings with chamber dimensions.
Trust me, you don't really want a huge bowl. Millions of smokers over hundreds of years have figured out what size bowls work. When I was a fairly new smoker I made a bunch of pipes, and figured that bigger was better. My large bowl pipes never get used, and I couldn't even give them away.
