I've come from a pile of "bad luck" with Epson units - and I've come to the conclusion that if it ain't broke . . . I feel that if you have a good working unit and it's cooling for about 90 seconds or so at shut down and the pic looks great - you should be good.
If it turns out that 1.03 becomes a real issue (who knows?), you have recourse since it's what the gave you - and they'll fix it. My feeling is that if you send in a perfectly good unit, you might get one that will disappoint.
Just my two cents.
