Looking up the specs, it doesn't seem to be anything special. It's an average 19" shadow mask that doesn't even do 1600x1200. It's only $10, but I wouldn't consider it a steal since it's not great at all.
Unless you want to use resolutions other than the ratio of that display, 1280x960 sounds like the maximum it will do in 4:3. It does 1600x1024, but that's like ~16:10, which means you'll have cropping or stretching using it, and 1280x1024 is 5:4 and would have the same effect (albeit to a lesser degree).
The vertical pixel amount that is often the strain for the CRT guns. It's more time consuming to go back across the screen and start a new row versus making it wider. Since the highest it does vertically is 1024, I presume 1280x960 is the highest it does if you want a 4:3 resolution.
If you don't care about higher resolutions nor more than 120Hz, and will be running at 1024x768, then it meets what you want and it sounds alright though.
Edit: It seems the specifications I found are wrong. Some are claiming it does 1600x1200 @75Hz. That makes it an average 19" shadow mask CRT. Something like 1400x1050 or 1440x1080 (both will likely need to be custom created) will probably be a good sweet spot for that size. Again, for $10, it's not bad, but it's not a better CRT model.
