i found something that may be of use for you
Ego Lv1 - more efficient, easier maintenance, re-positioned airways so no macroline, re-designed hammer assembly makes it super gentle on paintballs (in theory); but new design makes it feel longer, with the foregrip/reg extended to house the lpr (looks ugly now).
DM13 - shoots smoother, quieter, always gentle on paint like all DM's; but as with all spoolies, maintenance takes a little more patience, with the bolt assembly being multiple pieces with multiple o-rings.
i got this from Yahoo asnwers, as for the Luxe...there isnt much on it, but i would get the Luxe, Russian Legion use it, ( not my favourite team or anything ) and they stormed Division one and got straight back into pro ( i think it was div. 1 ) and also, Luxe's look so sexy annodised
