Reply to mixers w/ dual USB inputs

i'm in the market for a cheap to medium-priced mixer, and i stumbled upon the DJ-Tech DJM-303:



i have an i-Mix Reload and am quite satisfied with it, so i have no qualms about the brand. also, i'm drawn to this particular mixer because of the dual usb inputs. so i have two questions:

1. does anybody have any experience with this mixer?

2. does anybody know of any decent sub-$500 mixers that have two usb inputs?
