Here's an EXAMPLE (USA link):
http://pcpartpicker.com/part/asus-monitor-vs239hp
- $145 after MIR
- IPS panel (better viewing angle/color)
- 1920x1080 @60Hz
- 23"
- NO speakers
- good customer reviews
Refresh rates FASTER than 60Hz (to allow more than 60FPS for games) tend to be more expensive and not have IPS panels. So there's PROS and CONS to every monitor.
I personally have a 27", 2560x1440 IPS monitor. I don't care about gaming above 60FPS, it's the size, resolution and picture quality that I really care about.
That's probably above your budget though.
There are also some awesome G-Sync monitors coming but they're expensive. $400 and up, and require a GTX6xx or newer graphics card.
