I've tried to do the same with the Panasonic Lumix 20mm f/1.7 Pancake lens, although I must say the index is far from complete, with only a few number of countries included. I chose a lens, rather than a camera body, since cameras become obsolete, and go on clearance sale after some time. This lens is still pretty new and popular, and is less likely to be subject for various rebates.

The conclusion is not surprising: It's best to be a consumer in a big market.
