Thanks, retromangia. I actually did have a 29" Sony Wega CRT TV for all of my classic gaming, but I was wondering about these plasma TVs specifically for 480p gaming (and mainly 16:9 as well) since I found a couple for around $200 and $250 but I didn't know whether or not they were good enough (and there's a high cost for shipping them too).
By the way, the reason I say I did have a 29" Sony TV is because I sold it to get a couple of monitors (for RGB and S-Video consoles I have) but now I'm regretting that. These are great (a 14" Sony PMV and a 17" JVC broadcast monitor) but I'm missing the size of that Sony TV so much I'm thinking of getting one back. I had this issue of space and weight (that one because of the furniture I was making to house all of my consoles in a more tidy manner) and thought it'd be great to go to a higher quality image while losing screen size, but I'm finding that to not be as good as I thought it'd be.
I had that TV for four years, so maybe I'm just missing it now and it'll get better, but I'm really thinking of going back.
Anyways, I'll try and find more info about these plasma displays and post anything I can find here. Thanks!
