Best CRT for Wii gaming?

You wont find many (any?) 480p native CRTs anymore. That's EDTV resolution, and once HDTVs hit the marketplace it was largely abandoned. That Sony 960 is a 1080i HDTV and will upconvert a 480p signal to 1080i. I think 480p CRTs existed once, 20 years ago.

The difference between 480i and 480p is negligible on a CRT as a CRT can display interlaced sources properly without conversion. That's the beauty of CRT tubes and rear projectors: they're not fixed pixel displays and can display a source in it's native format without needing to scale, de-interlace or otherwise resize the image.

CRT tubes are needlessly bulky for being as small as they are and if you go flat screen and/or widescreen the weight to screen size ratio is going to be that much worse! I still have an old 27" toshiba cinema series (standard def) tube that I keep around for classic games and Wii looks great on it but not to the point that I wouldn't just want to play it on one of my HDTVs. Standard def tubes are much cheaper (and lighter) and easier to find as just about everyone had one. I really don't think you're going to notice much improvement with an HD CRT tube. Of course, you could always go CRT rear projection! All the benefit of a CRT tube with a more modern screen size.

Personally, I'd rather just dedicate an inexpensive 42" 720p to the endeavor and call it quits. Panasonic plasmas have ~16ms of lag which is practically non-existent. You may even be able to find a used EDTV plasma (480p) for a decent price but you're still fixed pixel so there's really no reason not to stick with a 720p as the PQ will undoubtably be better on the newer display and you can use it for things other than Wii.

The Sony will display what it's fed in it's native format, so:

480i in, 480i out
480p in, 480p out
1080i in, 1080i out

Sony KV 32HS420 http://www.hdtvblackfridaysales2011.com/Sony_KV_32HS420_32_Inch_Trinitron_HD_Ready

I got mine off Craigslist, 40 min drive to get it

The XBR960 is arguably the finest CRT even made, but I'm not shocked at all by those delivery quotes. This thing weighs a ton. You need 2-3 people to move it.

that's some serious Wii gamer

I had a huge, Sony 32" Trinitron that had hd inputs. The thing took 4 people to move but it was amazing for Wii and Xbox gaming. I found it for $100 at a church garage sale, had to leave it in the last move because it was just too heavy. If I remember correct I think they also made a 40" version. The best gaming tv I've ever owned.
