another speakers request thread :) 5.1 system

trying to decide on a set of 5.1 speakers.



i'd like to be able to use them for both my laptop and my tv. i want to keep them around $100-150.



looked at the logitec:

z506

x540



seems like the 540's are a bit better quality (based on the reviews).. but i'm not up to date on my audio equipment. any other suggestions welcomed



thanks
