I bought the SLA-2 off of e-bay for only 269 and free shipping. The listing didn't say whether it was new or used, but it was from a pro audio business so I assumed it was new. After I purchased it, I received a e-mail saying that it was "B" stock, and I can upgrade to "A" stock for $11.00. I scrambled to find out what B stock really means, and worried that it was a floor model or something. Too late, they shipped it before could make a solid decision. When I got it, it was in it's factory sealed box, what a relief! There is a tiny dent in the box. That's it. Is that what they determined it to be B stock? Heck, if that's the case, every box delivered by UPS turns in to B stock by the time it's delivered.
