Dominion78,
Care to elaborate on the reasons given by Mr. Pass behind the X350.5 recommendation? I also have the X350.5. But from what I have read on various forums so far, there seems to be more people recommending the X250.5 over the X350.5.
Maybe the reasons are fairly obvious as Pass Labs has been submitting mostly the X350.5, not the X250.5, to various magazines for review.
