I use a ViewSonic VP2365wb at work. 23", 1900x1080 pixies, 178°x178° viewing angle. $300 at Newegg.
You want a monitor with 178°x178° viewing angle which means it's a IPS type display. The VP2365 is the cheapest IPS montitor I could find. PVA monitors are inexpensive and also support wide viewing angles, but quality can be an issue depending on manufacturer.
To fix your other monitor, you can take it apart and replace the bulging capacitors around the switching power supplies. I've taken in
4 dead monitors and replaced the bulging electrolytics. Now I have 4 perfectly good monitors. Only expect your monitor to last about 2 to 3 years before needing a capacitor change-out.
