It’s so hard to find the 50mm for NEX in US stores that this might be a good deal even if you have to pay a $50 extra for it! Pcnation is right now selling 13 of them through Amazon (Click here). If you still want it for $299 than you will have to wait 4-7 weeks (according to Amazon).
Meantime the A57 is in Stock at Amazon (Click here), Adorama (Click here), BHphoto (Click here) and [shoplink 12322 ebay]Sonystore ebay (Click here)[/shoplink]. But Sony Japan keeps saying that it has been delayed and release date is April 27th ?!?!?!
