Pujols, Jeter, Utley, those guys are going to cost you more than if you get a common player that has impressed you in some way. Especially if you want to get three of each. Some decent players to consider would be Darren Daulton, John Kruk, Mitch Williams, Mike Lieberthal, Lenny Dykstra, Pat Burrell, Bobby Abreu, etc from previous teams. Jim Bunning and Robin Roberts are fairly low-end priced HoFers if you want to go that route. Richie Ashburn has some pricey cards, particularly the cuts, but most of his cards are affordable. Werth and Rollins are viable from the current team but there are so many 1/1s and low-numberd cards for current players it is still challenging. Schmidt, Utley, Howard and Carlton are forgone if you are looking for a cost-saving player.
Just some thoughts.
