The 32" 4:3 Sammy has a list of $999.00. You could probably get it on sale of $100 less from a big chain retailer.
I am not sure what features the Sony model has but in terms of picture quality, once tweaked the Sammy will yield very very good results. In my opinion Sony is not ahead of the rest of the pack anymore. They still have substantial brand name recognition tho. I have found Sony, Toshiba, Samsung and Phillips all to yield great results once calibrated. I have been researching a demo-ing widescreen tube tv's for the longest time. So I would look at quirks, features and reliablility as the determining factors. If the Sammy has all the features you want and costs less and you don't mind taking the Sony back then I would certainly recommend it.
Just one note about Samsung's TXM/TXN series. You must setup with an AVIA dvd or similar. For some reason Samsung will not ship these sets with quality factory settings. Expect bad geometry and red-push (which are easily corrected). Samsungs pre-set modes (Dynamic, Movie and Standard) are all useless. Their color temps (Cool 2, Cool1, Normal, Warm 1, Warm2) are also way off. Can't comment for Sony's temps but my friends Toshiba temps were also way off as well. So bottom line after purchasing a Samsung you will have to enter the service menu to correct red-push, turn down or off VSM, correct grey-scale, and of course correct geometry. Just make sure to record all the original factory settings before you tweak. Once performed you will be amazed at the transformation.
Lastly for Kensai, my unit does not have DVI but in the service menu is a bunch of PC settings under the DVI menu, so I am guessing they are PC compatible. When the DVI models come out go to the store and confirm.
