To answer the question, avoid ALL OF THEM. Who would someone go to for support if they have a problem?
It would be interesting for someone to take one for the team and buy a pair of these, then dig for info, based on the van's VIN and license plates, get photos of the guys in the van so facial recognition can be used.
The ship to address is WalMart. If Homebuys is selling them, it's probably not as an authorized reseller because WalMart isn't a Klipsch distributor, so there will be no warranty.
If you want to find out if Homebuys is a real dealer, you can contact Klipsch by phone, or on their website.
