Leaving for Paris on monday. I totally forgot about my Nikon D40 digital camera. I have no european plug adapter. Where can I buy one in Chicago? Radioshack says they have them for $10, though online they are only a dollar. Is this my best bet though. Also are there any sets available. I will be going to Thailand in 10 months so I will need one then too, but I have time to get that online.

My GF wants to take a hair straightener. It says 110V so I assume I need a voltage converter. There is one for $25 at Best Buy. Walmart is $20 but its much further away and my GF refuses to shop there. Is the Best Buy one my best bet. Seems silly to pay $25 for a voltage converter for a $20 straightener, but maybe I can ebay it or something when we get back.

The voltage converter comes with plug adapters. Could I use this on the battery charger for my camera or do I risk damaging it. The charger says it uses 8.4 V but can be used from 110-240 V.

So tell me what I need to buy and where to buy them in Chicago. We will be in Paris and Berlin.
