You're confusing yourself. And not listening to what people are telling you. There is no one set of dollar values that is right. If you're playing in a 10 team NL only league with 16 man rosters, your dollar values will be drastically different than someone playing in a mixed league 14 teamer with 23 man rosters.
Let's think about what auction values are. If you are playing in a 10 team league with one catcher spot, the 11th best catcher is worth nothing to you at auction, he will be available for free after the draft. Make sense? The only reason you should pay any amount of money for a catcher is if he is in some way better than what you can get for free. If he's worse than what you could get for free, you'll see a negative value. So the question is how much better is catcher A than the replacement level catcher available for free? Quantifying this is what lets us calculate auction values.
So you can see that league size and roster configuration
must be considered when establishing values. You are comparing apples to oranges, and maybe none of the sites you've looked at match the league you're actually playing in. The link you posted to Razzball assumes a 12 team league with this roster: Yahoo! Roster Format - C/1B/2B/SS/3B/3 OF/2 UTIL/2 SP/2 RP/4 P. Your Rotochamp link assumes: Positions: (1-C, 1-1B, 1-2B, 1-SS, 1-3B, 4-OF, 1-Utility, 1-CI, 1-MI, 9-P) so of course they're not going to agree. You can pick the one that "looks right" to you, or you can find something that was actually created for your league size and configuration. Also remember the auction values are driven by projections. And you are going to see different projection sources everywhere. Your best bet is always to do your own projections and calculate values yourself. But if that's not an option, and least do enough research to know you're not shooting yourself in the foot.
