Good 5.1 Speakers for under $100?

[Iamazn]

I'm currently looking at the Logitech Z506, which is $80 on Amazon. Are there any better 5.1 speakers for under or around $100?

I have had the Logitech X-540 for years and never had a problem with them!
The reviews on the Z506 seem pretty good...

I have not seen any other 5.1 speakers on the web for less then $100.
I say go for the Z506 set.
