Reply to Numark 4Trak - how portable?

Hi

I'm trying to decide on a new Traktor Pro controller and it's down to the Denon DN-MC6000 and the Numark 4Trak.

My preferred option is probably the 4Trak because of build quality and button layout, but I'm a little worried about how easy it's going to be to lug around. I have gigs I have to take the train to, and then travel across London by tube etc., and the 4Trak just looks like a really big unit, and heavy too. Also can't find many bags that will take it, and practically none that will carry the controller and a 17" Macbook.

Can any 4Trak users perhaps advise on how things are working out for them? Is the extra size and weight a problem, or are there ways to get around it? I don't mind a bit of physical effort, as long as the whole thing isn't so unweildy that it's just unworkable.

Thanks in advance for any feedback. Really excited about this purchase!
