You can pick up some very nice estate pipes for around $40-$50....much better quality than you can new. That being said, a Brigham, or Lorenzetti are good, inexpensive new buys.
There are a lot of dealers that sell cleaned, refurbished estates for really good deals, too, such as smokingpipes.com....a great way to get a better-quality pipe for 1/2-1/3 of what it would be new.
If you have any questions on any particular brand/pipe, please ask, and we will be happy to help.
