I'd go the other way and just get an Arcade. If you're not going online now, there really is no big use for the hard drive. The 512MB will be enough for game saves. And if, by chance, you *do* find youself wanting to get online, you could always find a used 20GB HDD on ebay for like 30 bucks. This way, you'd have the best chance of getting the newest hardware revision and you'd pay less to have the full hard drive functionallity.
