There is (not many polar bears collecting, although some of my friends are pretty hairy) I don't know if you're in the US, but we generally feel that the Global shipping program has discouraged our purchases from eBay US sellers a lot. Postage fees for a simple NES cart are out of this world. Personally I buy a lot of stuff from Japan, but I'd like to get more US stuff, if the price was right. Text-heavy games for example.
The collector scene in Finland is kinda two-fold - some more "advanced" collectors collect USA and/or japanese imports for the sake of running the games at 60 hz and some - especially those that have started later - collect purely the PAL B (SCN) releases that sold here originally. The inflation on some releases, like Mega Man games, is through the roof. That's why I've been unloading what PAL releases I have left for the NES, since I am getting that RGB modded AV Famicom as well.
That's why I did figure that maybe a fellow collector would have a spare Power Blade for me. I'd of course pay honest shipping fees.
