Sorry I didnt notice your post until i came on to research something. I know it's 3 months later but... Here's your answer. I ended up paying $760 each for 2 new tivo XL4 premiers with lifetime service. (You can probably pay less now) Trust me when I say this - once you get HD channels, you REALLY need all the space you can get to save the shows. Get the largest drives you can. I'm about a month away from having to get a usb drive and set up pytivo for storage holding. The Mecum auto auctions in HD are taking up 20 hours of hd video space alone. I had a problem with the DTA a few weeks ago where they were causing the 2 xl4's to lock up. So I disconnected them completely. If you are in Coral Springs (Advanced Cable), you do not need dta's with tivo HDs or Premiers. The biggest problem was setting up the cable cards. You'll go through phone techs over and over until you get one who cares about fixing your problem. If you are going to pick up the cable cards, try to go there during the week. The weekend warehouse is closed. If it doesnt work, your out of luck until Monday. As for the package you get, they'll give you a discount for several months for you to try everything. Take advantage of it. The new channels are good. Try them out before you decide. If you have flat screen tv's that measure 35 inches or larger - get the HD package too. Your price may vary but I think they gave me everything (except pay channels) for half-off for several months. Good luck. With the cable cards, sometimes it feels like Russian Roulette. But be persistant.
