While the D* MLB EI package looks good, so does the MLB.TV internet option. $110 for the year, HD picture if you have good bandwidth, built-in DVR functionality, picture in picture, available from any computer (take it with you when you travel), and more.
The option of watching something on TV, browsing around the web, and having a game (or two) open in windows on my screen, is attractive.
They've added some nice enhancements to this service for '09. I like the archives too, where you go to watch any game, even locally blacked out games, 45 minutes after they end. Or watch a highlight reel from any game.
