Bank accounts with over $100K? Make sure it is insured

With the recent market turmoil, I looked to make sure our company's basic finances were properly protected. FDIC insures up to $100K on checking accounts, and with some other allowances can go higher (joint accounts, retirement accounts, etc). But this wasn't enough for us.

Just found this on the web: http://www.cdars.com

Supposedly it is a network of FDIC insured banks that work together so that all your accounts are FDIC insured -- up to $50MM. And you only still work with that one bank.

There are probably other networks out there as well. In this economic climate, make sure you're protected!

Anyone else with better strategies, speak up!
