Recommendations for good quality and affordable PC speakers?

[Snouzer]

Hello, I need a pair of speakers for my PC, that don't cost a huge amount, but are still decent quality. Also, if my current speakers are good quality, then I won't bother buying anything else. (I don't know how to tell if they are good quality).

I currently have these: http://www.amazon.co.uk/Logitech-Z200-Speaker-Midnight-Black/dp/B00FSF2OSS

Thanks for any input

For the price they are decent.
