American Audio Radius 1000 vs Radius 2000

[neveronyx]

Right well I have a dilemma here thats seriously pissing me off.
The American Audio website is terrible and there aren't many reliable reviews of the Radius 2000.
Thomann.de lists the Radius 1000 as roughly $50 more than the 2000 model. Although both seem to have the exact same features and usually a model called "2000" would be more expensive than a "1000".

Is there anyone who has owned any these - particularly the 2000 - who can give some sound advice as to which model to choose?

Radius 1000- cd, midi controller
Radius 2000 midi controller, usb stick port
Radius 3000 midi controller, cd player, usb stick port, sdhc port

all the other feature are about the same. Those are the main key differences I see.
