RP Nathan's value in a trade?

I'm looking to trade away Joe Nathan. What should i expect in return? My team needs are 1B and 3B (I have Huff and Figgins). 4 teams have offered me a trade for Nathan straight up:
1-Loney and Encarnacion
2-Sandoval and Zimmerman
3-Beltre and SP Galaraga
4-OF Cruz and Delgado

Which of the 4 offers should I accept? Should I hold out for more? My OFers are Braun, Hamilton and Hart. Thanks for your help and advice.

None of them are worth it. Huff and Figgins will be better than all of them. Loney and Encarnacion is the only close trade but I have little faith in Encarnacion putting it together.
