Ask Mike www.briarblues.com if he's got pipes at your price range, he will treat you better than anyone and smokingpipes.com actually puts the pictures of the exact pipe you are buying. You can also ask Samthecoffeeman or however his name is spelt on the forums, he restores many pipes and sells them for very fair prices. You can also haunt our buy/sell/trade section, our prices there tend to be rock bottom on all pipes, new and used. Unlike Ebay, pipes sold in our forums tend to have all the flaws pointed out and nothing is left for the buyer to discover.
My honest opinion though the Savinelli unfinished pipes they were talking about earlier are probably your best bet for a cheap, high quality pipe. Also the Savinelli shell pipes are really awesome and cheap as well. I'd suggest avoiding Petersons, lots of quality control issues (and they tend to smoke hot), although they are the coolest looking pipes on the market for their price. Bjarne are occasionally mentioned, I feel they are just not all that popular as there's so many choices to be had, I've only seen people saying they love them, never heard anything bad about them.
