Yes, it is the 640U. It is regularly $79.99. This week it is $20 off bringing it to $59.99. There is a rebate form in their rebate flyer for $30, bringing it to $29.99. I just picked one up. The big difference that I saw with the BU besides the front panel controls is that it is true 42 bit, whereas the 640U is 36 bit. As a sidenote, OM has replaced the one mailing, one check rebate system with a flyer of individual rebate forms that you have to send to individual addresses. So we're at the mercy of the manufacturer's rebate fulfillment centers. So I'll be out .99 in stamps for my free blank cds, free ink pens, and $30 scanner. I can live with that. The scanner even comes with a USB cable so I don't have to feel guilty about getting one from Outpost again this week when I just ordered one for the Compgeeks USB hub last week.
