I have a Tinder Box here locally that sells only SMS meerschaum.
For the $50 - $80 range, they're fine. The problem is, they don't seem to improve in draft quality or carver competence if you spend much more than that, especially on the figural pipes. I have one Dublin-shaped meer by SMS, and it's alright. The draft hole is pushing to the "restrictive" side and it must be kept clean and clear pretty much during and after each smoke.
All SMS pipes are block meerschaum, and provided you get what you want style-wise, should perform adequately. I'd buy another one if the price was right and the shape was decent (I'm not into figural pipes). They seem to excel at the "lattice" patterns, I've noticed.
It's hard to look toward SMS when smokingpipes.com has IMP pipes with slightly better carvers, for roughly the same price.
