I got the Viewsonic 37" a couple of weeks ago. At first I was a bit put out by the SD PQ, however with the help of this forum and those participating, I've tweaked the settings to the point where we are quite happy with it. The guys at Costco told me the only 37"'s they got returned was a couple with audio issues.
I don't have any complaints as of yet and will most likely keep it. I'd say if you like what you see so far....get it and set it up. Once you get it in your place, you'll really see whether or not you like it.
