I'm up for an upgrade in a month or so, and I want to break away from the WiFi tethered iPod Touch, and currently, the only versions I can afford ar either a new 8GB 3G, a 16GB 3G Refurb, anda 16GB 3GS Refurb. Now, I'm all for more space for my crap, but is getting a refurb too risky? Should I just stick with 8GB like on my iPod for new 3G, or get a larger refurb?
