I just discovered SiteJabber, and thought it would be a good resource, but some of these reviews are way off. I have ordered from Thinkgeek about 5 times, and it has been a great experience. You cant beat their geeky selection. I called about a defective item about 3 months after receiving it, and the sent me a new one, no questions ask. Outstanding.
As for the Sitejabber reviews (in all), very questionable.
