Logitech G400 and Sidewinder X4 are what I use. I don't believe they're the best peripherals but they're probably the best for their price.
Sidewinder X4:
+ Good back light, auto profile switching, no key blocking, macro keys
- Keys are tightly packed, spongy keys (membrane), surface needs regular cleaning
Logitech G400
+ It's the MX518 with a faster sensor, 1000Hz polling, the new software is decent
- If you didn't like the 518 you wont like this
Use the earlier Intellitype software, 8.0, if you get the X4. The latest version has broken auto profile switching.
