I placed an order with BJ for the 6PX Pro and since I'm about to move thought I would call a couple days after to see when it would be shipped. I was then told it was backordered. I wasn't very happy. It doesn't say on their website and they don't have the customer service to send out an email to even let the recipient know to expect a delay.
I just ordered a 4Sevens 123-2 R5 from 4Sevens at 11:15am Wednesday with priority shipping. I emailed at 11:40 to ensure it was in stock and they responded with a tracking # saying it had already shipped. That's good service!
