If MCab is going for $$45, then definitely look into someone like AGon (maybe $35), Tex (same as AGon), or even Morneau/Morales who can go for just under $30. Youkilis is good as well, also will have 1B/3B flexibility. Of that group, I say AGon is the best there, then it's really a toss-up with the others.
I am very high on Felix Hernandez, so if your league wants to break the bank for M-Cab, perhaps go for the easily-top SP.
Finally, welcome to the Cafe! I didn't notice until now that this is your first thread here. A lot of great info on this site, you'll get a lot out of it.
