I think the box is going to be a steal for the price! Two SRX slots instead of one is also a very big plus. Have you guys seen Roland's promo video for this unit? Here's the link: http://rolandus.com/products/productdetails.aspx?ObjectId=897&ParentId=72

It's a good video. They demo a few sounds and explain the features.
