I was afraid Rokstar was no more when I couldn't find their site. Always sad to see a B & M or internet pipe retailer close shop. Jay had some very nice pieces, especially one by George Boyadjief that I very much regret not picking up.
If you're looking for a similar site that sells out of the ordinary or pipes by progressive and/or up-and-coming makers, check out
True North Briar of Alberta Canada. Cody has a good selection of pipes by some of the same makers that Rokstar handled.
I picked up two fantastic smokers from True North that were made by Martin Paljesek, a maker I wasn't familiar with. Rokstar, True North and a few similar sites led me to discover some outstanding pipemakers who would have otherwise remained unknown to me. For that I'm grateful and sorry to see Rokstar go.
