Which 65" Mitsu ? 813/713/613?

Ok, for a variety of reasons I've settled in on a 65" Mitsubishi set, but now I'm trying to get my arms around the key differences in the model line, see if moving up the food chain in these products is really worth it!


The 65813 is gorgeous, but this set is going into a custom cabinet, so the looks of the case are kind of irrelevant. The 9" CRTs sound appealing, but looks like it's gotten some slightly mixed reviews, maybe they're not as big a difference as you might expect?


Other then the larger CRTs are there are any other significant differences between the 65813 and the 65713? Or the 65613 for that matter?


Haven't had a chance to view these side by side, but certainly interested in others thoughts and opinions who may have already been down this road.


Thanks!
