I bought mine from 3ds-flashcard but it was soon after it came out so there wasn't anything on ebay yet. Their site is rather sketchy but I had purchased something there before so I was pretty confident. Since you have an ebay coupon I would go that route. They're cheaper than 3ds-flashcard as well.Awesome, these are great! Thank you. Second review definitely sealed the deal. Any specific vendor you would recommend? I have a $5 coupon on eBay right now and those vendors seem to be the cheapest (and sketchiest), so I might just bite the bullet and order from one of them.
