The price to begin with :snicker:
Ok solo2 has two built in sat tuners, you can't take them out & replace them. Where as duo2 tuners are inter-changeable. You can have two dual sat tuners or one dual sat tuner & one aerial type connection tuner etc etc. Duo2 can be fitted with a 2.2 or 3.5 HDD where the solo2 can accommodate a 2.5 HDD only...
Duo2 has a lcd screen on the front of the box along with the normal VFD display, solo2 has VFD display only. Spec \7 speed wise there is not a lot in it to be honest. Both are cracking boxes and are worth every penny in my opinion...
