I have since been bitten by baseball card bug that last had a hold on me in the mid nineties.  I wanted to grab a bunch of prospect and rookie cards along with some of my current favorite players.  As we all know things done changed in the past 15 years in the card industry and I'm looking for a good online source where I could find prices, breakdowns, and a place to buy cards.  Aside from paying for Beckett's online services are there any good free pricing guides?  Who has the best online sales?  Any help would be great.
