Techno I realize you have your own opinion but the fact is that Westone is renowned for their build quality, and the SMx v2 series has well-documented quality control issues. Every pair that has passed through my hands (3) has wound up being defective in some way, 2 of them having the shell fall in two pieces without warning (and I positively baby my IEMs, these are the only ones costing more than $50 that have ever broken on me), and I have heard others complain of the same issue. On top of that, the actual materials they are made of, as you will see if you ever have this problem, are far below the quality I would expect at this price. The cable is very nice overall, but the materials used in the shells themselves are positively insulting for a $350 piece of equipment targeted at the professional market.
That said, IMO nothing that I have heard, fullsize or in-ear, matches the SM3 for overall sound quality (resolution, detail, tonal accuracy) at the $350 or below price point. Their sound is absolutely magical and, according to some, compares favorably to customs costing up to twice the $350 that soundearphones asks for them.
I haven't used them but I'd guess that they're pretty reliable when it comes to shipping times. If you can get a hold of them by email you might want to ask, but I'm glad to see your getting another SM3 after what happened to your old pair. The V2's build quality seems as good as the Westone IEM's and if you treat them well you shouldn't have any problems. I've been luck a few times getting the cables snagged but nothing has happened even on once the left housing was ripped out of my ear with the tip still in my ear so you know it got pulled out with some force.
As you know they're just a great sounding IEM and one that I think is well worth the price.
