Logitech Z680's, who here has them?

I'm thinking about getting these expensive MF's:) but I was curious if anyone here has them and how do you like em?  The Altec Lansing 4.1 speakers that are STILL being offered on Dell's site are OLD!  These things have been around for years.  When are they going to upgrade their selections?  I remember reading nothing but complaint after complaint about the Altec's about hissing and cracking speakers etc.

Anyways, if anyone has the 680's, please respond and give me your thoughts.

Thanks.
