I'm considering buying an Xbox for my boys this Christmas and I want a little 3rd-party advice on which version to buy. I know I need a Jasper chipset and I want at least two controllers. We will use Xbox Live a bit, and I like the idea of a hard drive for saved games, but I already have a TiVo for Netflix streaming. I'm looking at the following options... $199 Arcade +$49 20GB refurb live starter kit w/ 3mos Live Gold $299 Elite (120GB HD & Lego Batman and Pure) I was going to save the $50 and spend it on a controller, but I'm second guessing myself and wondering if I will need the extra 100GB. Can anyone share their experience with using the hard drive? Will 20GB fill up quickly with Xbox Live Arcade stuff and saved games?
