Thanks for your replies.
Yes, overseas shipping costs and 19% import customs duties could make this rather unprofitable for me even in a group buy. Plus, I wasn't aware of where to get a shell for the Turbo Everdrive, and the price of the Stoneage gamer deluxe package is way out of what I'd be willing to pay.
I'll have a deeper look into the different stores that are selling Turbo Everdrives. I would be even satisfied with the more affordable
Low Cost Flash HuCard, but there are none available at the moment.
I was mainly interested in using it for some of the really expensive games, for the rest I prefer either original games or Virtual Console purchases.
