I've got two favorites, an Altinok and an IMP. You can find new IMP on eBay from a good dealer there who is probably associated with the manufacturers, who don't sell directly to the public. Otherwise, smokingpipes.com has a range.
My Altinok is the same as the one displayed on this page: Altinok Pipes® - AG128 AutoGraph 128
Altinok pipes are great, at least the Autograph series. Some of the cheaper models require you to upgrade for a higher quality stem, which seems like it's worth it to me. Frankly, I'd recommend selecting from the "ready pipes" if you want to get your pipe soon, Altinok also does made to order, but it takes quite a lot of time, sometimes longer than predicted. From the reviews I've read, most people are happy with these two brands.
