Smokingpipes.com is the front runner for online pipe and tobacco retailing, the pipe-by-pipe photos, and
a complete list of specs on each pipe. As I recall, Cup O Joes doesn't specify the shape, which leaves you
guessing if it is a subtle call, and they don't list weights; however C'Joes does have its own inventory where
you can get things you can't get other places. Other sites are somewhat awkward, in one way or another,
but mostly useable. In some cases, frustration can be as minor as not tipping a pipe slightly in the photo
to give a view of the thickness of the rim of the bowl. Some sites put the pipe in a little pipe rest, which
throws off the scale, so you don't know if you are looking at a traditional billiard or a pot, for example.
tobaccopipes.com leaves off a lot of specs on its pipes, but it does have the series of photos of the pipes
that allows you to gather a lot of information visually. I think smokingpipes.com has a number of younger,
tech saavy staffers for whom the site is a full-time job, and that really shows.
