I've bought a few estate pipes on eBay in the past - no issues; pipes delivered and I'm enjoying them. So I thought I'd go on line last night to see what's out there. I could not believe how many pipes were on line with broken stems. Some look like the owner chew their way through the smoke. I use rubber tips on all my pipes. I actually go to Ace Hardware and buy a couple feet of surgical rubber tube and cut it to size. I replace them every few months. It keeps the bite free of teeth marks and much more comfy on the ol' choppers.
