you can get a VU+Solo2 clone for around the same price as a DM800SE V2 sim 2.2 clone the processor is better in the VU+
if you can stretch your budget a bit further the new VU+Solo SE is out soon then you wont have any problems ie patched images drivers etc!
all the latest E2 images being released are big in size so you will definatly want a new box with a better processor and bigger memory if you want to run all the good plugins like IPTV XBMC etc etc!
