forsooth, I find that I frequent sellers that take the time, as you explain, to describe their product as fully as possible, and I automatically stay away from the ones that take the easy road of just posting a picture. For me, the exact specs and dimensions are important, and I guess I assume that a seller who doesn't provide this info doesn't want someone like me as a customer
Marty Pulver is a class act, as are the folks at smokingpipes.com. Others not so much:-(
One thing I always appreciate is the pipe on a grid that makes the dimensions visually clearer. I always liked that pipesandcigars.com did this, for example, but they have now ceased the practice, much to my chagrin.
In any event, back to the original topic. Here are some other less well known pipe sellers I sometimes enjoy, both new and estate:
www.pufferspipes.com
www.pipes2smoke.com
www.thesmoker.com
www.thepiperack.com

www.walkerbriarworks.com STRONGLY recommeded!!!
www.cheapestatepipes.com

As you can see, there is plenty of good stuff out there! Happy hunting!
