Some of the pipes i smoke most often were essentially free. I got them in lots of pipes i bought off ebay, recognizing one pipe in the picture of the lot that i wanted and unexpectedly got other pipes that were gems in disguise.
I dont really care how much a pipe costs, i care that it doesnt gurgle, is light enough to clench and is a classic shape that i prefer, either a straight billiard, dublin or canadian etc.
Expensive pipes are often weighty and cumbersome, i have some italian and danish pipes that smoke perfectly well, they just get in the way of an effortless smoke.
If i had eight gbd shape 124's from the mid to early 20th century, that might be all I'd smoke, but if i had the money to spend on a 35k dunhill, i might do it.
