I couldn't find one recent experience of anyone successfully buying a "new" MM20 from southerncross. I think it was active when RXW first went out of business and had to liquidate inventory, but now it might be an automated system that just takes your money. Maybe I'm wrong, I read lots of cautionary tales about them, but nothing definite. Seems kind of sketchy to me, you can usually find a genuine used RXW in the $900 - $1200 range. Might be worth waiting for..
