Yeah, that preview tool really could do with updating. It doesn't offer link units either.

Are there any proxy services (like anonymizers) that let you choose which country your proxy IP address comes from?

I find the preview tool useful, but what I really need, is to see the Ads that are actually displaying on my pages in their target locations.

I have pages intended for specific locations, but I have found no way of finding out if they actually display relevant Ads.

Proxy tools are useless because most search engines like Google keep a list of their IP addresses to prevent fraud. If you even manage to get a fast proxy connection all you will mostly see charity ads or blank spaces. We really need the preview tool to be updated to allow us to see if decent image ads are being served.

and also to be used with other browsers than the crap from Microsoft!
