They've been selling them for a while now, so I figure somebody here must have picked one up. What did they change? Do they run better? Better details? They shut down production for a while to re-tool, so I figure there must be some major changes, but nobody's posted anything about them. Are they worth getting? I really don't have any use for a SD40-2, so I probably won't get one, but I could always use a GP7/9 switcher, which I assume are coming shortly.
