The cats out of the bag, i have been prospecting for several years and it appears based on rookie cards and autographs that anyone that is a "top" prospect has almost, i hate to say topped out in card value, but are expensive and potential upside is low in my opinion. Bryant this year for example. The fun part for me is doing my own research and looking for low level guys who have potential and whose cards are cheap or very reasonable. (fangraphs is one of my favorite sites).
good luck and have fun!
