You can get that at Bed Bath & Beyond for $455 minus the 20% coupon (doesn't exclude Blentec), making it around $363. Not all stores carry it, but if yours doesn't they should be able to order it for you at Customer Service with free shipping. That seems to be the best deal around on the new Designer series. I bought it and love it.
good call pikabb, that's exactly what i did (got the twister jar too for $120 less the 20% coupon, it's awesome for peanut/almond butters). we've had the designer series blendtec for a few months now and still use it almost every day. someone asked if it can handle veggies like carrots, and the answer is a resounding yes. we have yet to throw something at it that it couldn't handle.
