If you're in the SF Bay Area or Southern California, Fry's Electronics have these monitor arms for a bit less if the shipping is factored into the price. The catch is that they're only available for pickup and only three locations have them. Fremont (NorCal), Roseville (SoCal), Anaheim (SoCal).
nitronarcosisDid you have luck? I ended up ordering mine from Walmart. I don't live far from the Fremont Fry's, but still far enough that the drive wasn't worth "saving" a few bucks and I couldn't wait for the drop to become available again.
