If you want to buy Modo new, it will set you back $895.00.  If you take DAZ's modo 103 for $139.90 for PC members, then add the upgrade to 301 for $295.00, that comes to around $434.90 for version 301.  Let's see, $895.00 vs $434.90.  If you want to upgrade after 301 is released, then the upgrade is $100.00 more.  Still not a bad deal.
