I'll second that Rog !! Also the inclusion of the USB link is a BIG PLUS....

During a gig when you've finally got them up on the floor 'dancing' -- waiting for the Floppy Disk to load the next song set-up is a BIG 'No-No'. During the LOAD time, they'll be off to the bar and ordered the next round and probably be half way through it, before the next song starts LOL !!!
