Get the same exact 25" chassis (Wei-ya 825HR) from Alva Amusement in Miami FL. They cost $89 before shipping. I have ordered from these guys for years and they are good. They only take orders over the phone so you need to call and the receptionist is very polite. They also fix their chassis if they have issues pretty inexpensively, and have a tech you can talk to if you have questions.
As for quality on these- they are not going to compare to a solid performing WG or Hantarex. They do have a nice sharp pic and good color. However, when one color is dominant on the screen, you do get some wash out. The other problem is their default width is about 3/4" too wide for most monitors, even with the width minimized. (You can swap width caps to fix this if you have the means) If you don't care about these things, then they are great replacements and I've never had one go bad on me yet from normal use. Remember, they're only $89 and made in China so again, no WG or Hantarex build quality. But the bonus to these is they are so simple, they are very easy to work on and fix if they break.
